sync: merge main into develop after v3.3.0 release

Bring back the main-only content that develop has been missing:
- pyproject.toml chromadb upper-bound removal (#690)
- CHANGELOG [3.2.0] Packaging subsection (#690, #761)
- CONTRIBUTING.md fork-first clone instructions
- mempalace/hooks_cli.py richer block-reason strings (from #666,
  still used by the Python hook invocation path)
- integrations/openclaw/SKILL.md version bump to 3.3.0

Plus the v3.3.0 release commit itself (4aa7e1e) and the legacy
main-only commits (#666, #690, v3.2.0 finalization) for history.

Resolves the main → develop drift that caused PR #838's conflicts.
Going forward, back-merging main to develop after each release
will prevent the same pattern.

Single conflict in CHANGELOG.md resolved by taking main's version
(the Packaging subsection under [3.2.0]).
