Bump version to 0.2.2

[neuromechanist]

Summary

Release-prep for 0.2.2, which ships two post-0.2.1 fixes already merged to main:

• pamica.__version__ stale (hardcoded in version.py, not synced) #182 / Derive __version__ from package metadata #183 — pamica.__version__ now derives from package metadata (was reporting the stale 0.1.2 even in the 0.2.1 wheel).
• Sweep pyAMICA -> pAMICA URLs after GitHub repo rename #184 / Canonicalize pyAMICA URLs to pAMICA #185 — pyAMICA -> pAMICA URL canonicalization after the GitHub repo rename (fixes the 404'd eeglab.org/pyAMICA docs links, updates repo URLs / badge / resolver default).

Adds the 0.2.2 changelog section and syncs the version across pyproject.toml, CITATION.cff, .zenodo.json and uv.lock.

Release plan (after merge)

Tag v0.2.2 on the release commit and cut a GitHub Release, which republishes to PyPI (with the corrected __version__ and links) and re-attaches the native binaries.

Test plan

• sync_version.py check 0.2.2 passes; all four files agree.
• uv build -> pamica-0.2.2; twine check PASSED; built package reports __version__ == 0.2.2.
• mkdocs build --strict clean.
