feat(status): add `make status` for compact health summary

scripts/status.sh prints a six-line summary composing existing checks:
- audit + doctor (one call, since audit.sh runs doctor internally)
- canonical/mirror sync state via sync-check.sh
- open todo count under * <Project> Open Work
- inbox count (excluding .gitkeep and PROCESSED- prefixes)
- git working-tree state with ahead/behind upstream

Sample output:

  rulesets status — 2026-05-28 09:13 CDT
    audit  Summary: 41 ok, 0 warnings, 2 failures
    sync   canonical = mirror
    todo   22 open
    inbox  1 unprocessed
    git    main dirty — in sync with origin/main

The script adds no new logic beyond formatting. `make status` is the
entry point.

The scope here is limited per the triage disposition for codex item
#12. The rest of #12 was rejected. `make sync` duplicates the existing
sync flow, `make health` wraps existing checks without adding signal,
`make bootstrap-project` duplicates `install-ai` + `install-lang`.
