Adds a `tools` subcommand group to the zea CLI, with the selection tool as its first entry (`zea tools select`), and brings that tool up to the standard of the rest of the package. CLI - New `ToolsArgs`/`_Select` dataclasses in `zea.cli_args`, so `zea tools --help` renders without importing keras or matplotlib; the implementation is imported lazily in `run()`. - The docs page picks the new subcommand up automatically through the existing `tyroprogram` directive. - Every subcommand dataclass now exposes `run()`. `zea.__main__.main()` is a parse-and-dispatch, and `zea.data.process`/`zea.data.app` reuse the same dispatch instead of duplicating the argument forwarding and the Gradio launch. Selection tool - `print` -> `zea.log`; docstrings rewritten and brought in line with the code. - `main()` split into testable pieces (`load_input_files`, `compare_images`, `annotate_sequence`, `save_masks`, `save_mask_animation`, `run_selection_tool`); every prompt is skippable through a CLI flag. - Annotations are saved as a zea HDF5 file (`data/image` + a single-label `data/segmentation`) instead of a bare `.npy`, so the result reads back with `zea.File` like any other dataset. - zea files are accepted as input, including `hf://` paths; the image grid's coordinates are carried over to the saved segmentation. - Output paths are guarded before annotating, so a name clash cannot throw away the selections that were just made (`--overwrite` to replace). - Fixes: closing the plot mid-selection no longer spins forever; a sequence with <= 3 frames no longer raises `NameError`; mask overlays in the preview animation are drawn semi-transparent instead of hiding the image. - Removes the `interactive_selector_for_dataset` stub, which only ever raised. zea.tools.__init__ now lists what the package contains and which entries are CLI tools. Tests: 70 for the selection tool (widget stubbed, everything below it exercised for real, including zea-file round trips) and 5 for `zea tools` parsing.
Fixes two problems from a real macOS run of `zea tools select`:
- The confirmation dialog created a second Tk root next to matplotlib's own
TkAgg interpreter, which aborts the process on macOS (Tcl/Tk 9 + `-[NSApplication
macOSVersion]`). Confirming now happens with a keypress in the plot window
('enter'/'y' to keep, 'n'/'escape' to redo, closing the window keeps), so the
tool no longer switches the user to the terminal between key frames and no
longer needs tkinter at all. The accept/redo keys are checked against
matplotlib's own keymap by a test. The "press Enter when done" prompt for
open-ended selections moved into the window for the same reason.
- `zea tools` no longer calls `init_device`. It is interactive matplotlib work;
only the optional image-mode metric touches keras, and that runs fine on the
default device.
The remaining tkinter use in the selection tool is the file-open dialog, which
only runs when no paths are passed. It now falls back to typing paths on the
terminal when tkinter is missing, instead of raising. `zea.internal.setup_zea` is
the only other user of that dialog left in the package.
- Drop tkinter from zea entirely. `filename_from_window_dialog` is gone from `zea.internal.viewer`; the selection tool asks for paths on the terminal when none are passed, and `setup_config` now requires `--config` instead of popping up a file dialog. - Carry the cheap fields of a zea input file into the annotation file: metadata, metrics, probe, us_machine, acquisition_time, and the image map's coordinates, timestamps, unit and range. The bulk arrays are left behind. Which fields those are is derived from `FileSpec.SCHEMA` and `Map.SCHEMA`, so fields added to the spec later are picked up without touching this module; only the small sets the tool writes itself, or that describe pixel values (and so say nothing about a boolean mask), are named here. - Prompts and status are drawn as a bold, boxed banner so they stand out against the image, and a preview window stays up through saving reporting what was written and where, instead of only saying so on the terminal. - Fix the CAMUS example path in the module docstring.
The banner listed both output filenames and their directory, which overflowed the
figure width. Both save functions already log where they wrote to, so the banner
just says "Saved" and how to close the window. Key hints lose their spaces too
('enter'/'y' rather than 'enter' / 'y').
- test_main_dispatches_to_run_processing patched run_processing with a fake taking `dataset, config, key`. That worked only because __main__ called it positionally; ProcessArgs.run() passes keywords, so the fake now needs the real parameter names (`dataset_path`, `config_path`). - The docs build failed on 6 "duplicate object description" warnings: an `Attributes:` block on a NamedTuple duplicates the field docs autodoc already emits. Documented the fields with `#:` comments instead.

- Update four help/doc sites that still described a graphical file dialog; paths are asked for on the terminal now that tkinter is gone. - annotate_sequence indexed mask[0] unconditionally, so closing the window without selecting raised IndexError. Closing now stops the annotating and keeps the key frames done so far, matching what closing means elsewhere in the tool; annotating nothing at all raises a clear ValueError. - setup_config suggested `zea --config`, but that flag belongs to `zea process`. setup()'s docstring still promised a window dialog for config_path=None. - Give `python -m zea.data.process` the same init_device() call as `python -m zea.data.app`.

main() initialized the device with the default 'auto:1', so the module entry point could not select one while 'zea process' can, even though its docstring calls the two equivalent. Add the same --device flag and pass it through.
interpolate_masks spread its masks evenly over the sequence, with no notion of which frame each one came from. Stopping early therefore misplaced them: with 6 frames and 4 key frames (0, 1, 3, 5), closing the window after two selections put the second mask on frame 5 instead of frame 1, and every frame in between got an interpolation that was never drawn. Truncating .astype(int) meant even a completed run placed the middle key frames slightly off. Give interpolate_masks an optional positions argument holding the frame each mask belongs to, defaulting to the previous even spacing, and have annotate_sequence pass the key frames it actually annotated. Frames past the last annotated key frame hold on to its mask, which np.interp already does for rectangles and the polygon branch now does by locating each frame in its segment rather than dividing the frames into equal blocks.

interpolate_masks only renders frames 0..num_frames-1, so a position at or past num_frames silently dropped its mask. Completes the positions contract next to the length and monotonicity checks.

positions is documented as frame indices and only whole frames are rendered, so a fractional position could never place its mask. Folded into the range check rather than added as a fourth assert.
main added a `datapaths` subcommand in the same four places this branch adds `tools`. Both are kept, and every subcommand list is now alphabetical (app, convert, data, datapaths, process, tools) rather than the previous ad-hoc order. main still carried the explicit if/elif dispatch in `main()`; this branch had already replaced it with `args.run()`. Kept the one-liner, which covers DataPathsArgs too since it defines `run()` as well. tests/test_main.py: both sides appended a subcommand section with the same trailing context, so git tangled them; each is reunited with its own body.
Path.with_suffix replaces everything after the first dot, so annotating clip.720p.mp4 wrote clip.hdf5 -- dropping the title and the _annotations marker, and with --overwrite clobbering any unrelated clip.hdf5 next to it.
The overlay loop was nested inside a zip over the metric scores, so --metric None drew nothing at all: the user picked two regions and got an unchanged figure back.
--num-selections is a plain int on the CLI, so 0 reached the 'nothing was selected' error and a negative value leaked out of np.linspace.
file.data raises for files with more than one track, so a multi-track input leaked an AttributeError. Tracks are now picked by label or index, and asking for none of them lists what the file holds.
python -m zea.tools.selection_tool dropped argv and prompted instead. It now parses the same _Select dataclass zea tools select uses.
ask_for_files checked Path.exists() on every answer, so it rejected the Hugging Face paths the --files flag and the module docstring advertise.
Sequence mode ends with a wait_for_key after saving, but image mode writes nothing and returned straight away, so the gCNR overlays and titles were torn down with the process. It now waits on the same --confirm flag, and closes its figures either way instead of leaking them.
log.set_level is a context manager, so calling it bare did nothing: the CLI has always run at the default level. Removing it makes that explicit rather than accidental -- making the call effective instead would silence the tools' prompts and 'saved to' messages, which are log.info.

The test re-implemented the matching loop, so a regression inside interpolate_masks would still have passed. The loop is now match_polygon_chain, which both interpolate_masks and the test call.
In 'max' mode num_vertices is max(sizes), so the guard could never be true and the diagnostic only ever reached 'min' callers. The warning is about the spread between polygons, so it compares the smallest against the largest.
The test brute-forced the optimal shift to compare against, which is the same search match_polygons does. The rolls are known up front, so the aligned polygons are simply base, base+20 and base+40.

The main merge replaced the load_dict_from_hdf5_group free function with File.load_group, which reads through the chunk reader rather than h5py's serial path, so _load_zea_file failed to import and every zea-file test errored out.
_load_zea_file resolved hf:// paths itself before opening the file, which both duplicated what File already does and forced a full download -- File streams by default, fetching only the byte ranges actually read. Unknown track labels now fall through to File.get_track, which already raises listing the labels the file has.

The tool always read data/image, which the --files help did not say. --key now names the map to annotate, defaulting to data/image so nothing changes unless asked, and accepts the fully qualified spellings used elsewhere in zea (tracks/track_1/data/image, data/image/values).
Adopts the resolution rules from the process CLI so the two behave alike and merge cleanly: labels are matched before indices, so a track labelled '1' is no longer read as index 1, and every way of naming a track that is not there raises one ValueError listing the tracks the file has, rather than a mix of ValueError/IndexError/KeyError. Single-track and flat-layout files now ignore --track instead of failing on it; they have nothing to address.
