merge: incorporate origin/main into community-mode branch

Resolved 10 conflicted files:
- VERSION/package.json: kept 0.12.0.0 (feature branch version)
- CHANGELOG.md: preserved both branch entry and main's new entries
- supabase/config.sh: kept GSTACK_WEB_URL, accepted TELEMETRY_ENDPOINT removal
- bin/gstack-{community-dashboard,telemetry-log,telemetry-sync,update-check}:
  took main's improved versions (edge function approach, safe cursor, UUID gen)
- supabase/functions/community-pulse: took main's count-based approach
- test/telemetry.test.ts: took main's structure with fingerprint field name

Post-merge fixes:
- Removed shadowed local RESOLVERS/functions in gen-skill-docs.ts (main's
  resolver imports now take precedence for tier-based preamble, coverage gates)
- Added 3 missing E2E_TIERS entries (ship-plan-*, review-plan-completion)
- Updated telemetry test to match current prompt text
- Regenerated all SKILL.md files
