Structural updates, require Python 3.8, deploy a WHEEL file

[FichteFoll]

This is an alternative approach to #178, using it as an inspiration but going about it slightly differently.

I tried to isolate commits into reasonable chunks.

Things I did:

• Update repository structure (rename st3 to src).
• Add pyproject.toml file with dev dependencies & using uv for our toolchain.
• Require Python 3.8, since 3.3 is finally being deprecated by ST.
• Remove vendor and combat folders since they are not necessary in 3.8.

Things I did not do:

• Ensure that tests can still be run with Unittesting.
• Test anything besides uv build.
• Reformat or add a formatter configuration.

Require Python 3.8, since 3.3 is finally being deprecated by ST.

IMHO, we should first create a py33 compatible WHEEL release, targeting legacy ST3/4 builds, to totally get rid of legacy dependency releases without breaking unmaintained py33 packages on ST3/4 platform.

A 2nd step then would be to upgrade code base to a py38-only version.

For python 3.8 it may be useful to disable annotation evaluation via from __future__ import annotations to save some CPU cycles.

Just so we are on the same page: This would specifically target ST3 & PC4 environments, right?

[deathaxe]

Yes, it would.

PC3 doesn't work or upgrades itself to PC4 automatically, hence it is the most likely one in use.

Majority of libraries are shipped via pypi for ST3/py33, already. Only those special purpose dependencies, aren't.

[FichteFoll]

Yeah, makes sense. How exactly does it work when I upload a wheel for, say 0.4.0 with Python 3.3 and for all following releases I would only offer Python 3.8 (and 3.13/14)? Does "the" dependency crawler go through several github releases until it the asset file pattern matches or does it only look at the latest release?
