v2.2.0 — Bug fixes, 374 tests, PyPI auto-publish

What's new in v2.2.0

Fixed

• __trainned typo renamed to __trained throughout map.py.
• reinforce() neighbourhood bug: radius now continues from 1.0 in rounds 2+, instead of resetting each round.
• Linear LR decay to zero: denominator changed from T to T+1 so the final iteration gets a non-zero update.
• IterativeSOM model-selection bias: emits a warning when give_best=True and validation_data=None.

Added

• CITATION.cff — GitHub "Cite this repository" support.
• 27 additional tests — 374 total, 99% coverage.
• .github/workflows/publish.yml — automatic PyPI publish on every GitHub release.

Changed

• CONTRIBUTING.md, README.md, and docs/ updated to reflect v2.2.0.
• run_cbf_som.py moved to examples/cbf_dtw_example.py.
