fix: repair cross-skill contract gaps and harden Tracker handling (v1.1.1)

- deploy: create "! Rule Needed" label on first deploy (was promised in
  frontmatter but never implemented; rule-review depends on it)
- rule-review: accept Bootstrap-mode entry (Phase: Bootstrap, no Tracker yet)
- survey: create the three artifacts before invoking handoff so handoff's
  sanity check no longer loops
- deploy: name manage_gmail_filter params explicitly (action/criteria/filter_action)
- rule-review: quote label query (label:"! Rule Needed")
- deploy: renumber execution-flow block to the 7 phases the body runs
- survey: frame Tracker About tab as a technical reference
- import + rule-review: de-duplicate rule_id before writing to Tracker
- survey/import/deploy/rule-review: document XLSX Tracker Drive round-trip
- all skills: use session date only in _status.md (no fabricated clock time)
