feat(session): ephemeral session model (epic #85)

[devguyio]

Summary

• Implements ephemeral session model replacing permanent workspaces (stories #87-#90)
• Adds session registry, workspace hydration, lifecycle management (start/stop/inspect/cleanup)
• Adds finalization subagent for preserving uncommitted work
• Removes bm teams sync command (replaced by session-based flow)
• Adds bm minty migration skill for existing installations
• Removes 11 dead integration tests that called the removed sync command

Commits

20 squashed commits (one per code task) covering 4 stories:

• Story #87 (CT-01 through CT-07): Session registry, workspace hydration, CLI client, status display, push with rebase
• Story #88 (CT-88-01 through CT-88-04): Session finalization, stop/force-stop, real claude launch
• Story #89 (CT-89-01 through CT-89-04): Inspection, cleanup, retention, daemon wiring
• Story #90 (CT-90-01, CT-90-02): Migration skill, sync removal, documentation

Known gaps

• Bridge identity provisioning and RObot config injection not yet wired into session hydration path (tracked separately)
• Config surfacing (ralph.yml, PROMPT.md, CLAUDE.md, settings.json) incomplete in ConfigAssembler
• E2e operator journey sync steps need replacement with session-based equivalents

Test plan

• Unit tests pass (cargo test -p bm)
• Integration tests pass (110/110)
• Conformance tests pass (18/18)
• Clippy clean
• E2e tests — 3 scenarios blocked by known gaps above
