Release 0.4.1

PyPI metadata refresh for category-search discovery.
No code, no test, no protocol changes — wire format and
public API are identical to 0.4.0.

Highlights:
- Description rewritten to lead with category-search phrase.
- Keywords expanded 12 -> 21 (category, framework, brand).
- Topic :: Scientific/Engineering :: Artificial Intelligence
  classifier added.

Companion changes (separate PRs):
- GitHub topics: governance dropped, mcp added (now mirrors
  cycles-client-typescript).
- runcycles/docs: Python framework integration guide titles
  retitled for category-keyword leading (PR #568).

v0.4.0 Dynamic subject and action fields on @cycles

Subject fields (tenant, workspace, app, workflow, agent, toolset),
action fields (action_kind, action_name, action_tags), and dimensions
on the @cycles decorator now accept callables in addition to constants,
mirroring the existing estimate/actual contract. Closes #45.
