Refine sync spec: in-repo skill, Teams webhook TBD, .claude/skills tracking

- Skill lives in-repo at .claude/skills/sync-nowai-leaderboard/ (versioned)
- .gitignore: ignore .claude/* but track .claude/skills/
- Notification: Teams incoming webhook (URL TBD), PushNotification fallback

+## Repo tracking / deployment
+
+- `.gitignore` ignores `.claude/*` but un-ignores `.claude/skills/` (`!.claude/skills/`), so the skill (`SKILL.md`, `sync.mjs`, fixtures) is version-controlled and travels with the repo, while personal `.claude/` config stays out.
+- Consequence: skill files ride along to the HF Space on push. Harmless — the Space serves only the static site and ignores them.

+## Open items / TBD

+- **Teams webhook URL** — not yet provisioned. Notification falls back to scheduled-run summary / `PushNotification` until the webhook secret is available; then wire it in.
