feat(observer): extend classifyTask with 7 new classes

Closes brain-retro 2026-05-20 #1 — analysis/memory-sync/regulatory-bump/
release/cleanup/monitoring/planning. Addresses '59% other' observation
from initial retro factor matrix.

Ordering: release before feature (merge feature-branch), planning before
refactor (план рефакторинга), memory-sync/regulatory-bump at top as most
specific. monitoring regex проверь состоян covers inflected forms.

9 new vitest tests, 241/241 GREEN in npm run test:tools.
