feat: cheap Rust audit + mmctl audit, gate tick on real issues

src/audit.rs (new, 8 unit tests passing)
  - AuditReport with deterministic checks: missing frontmatter, invalid
    metadata.type, dangling MEMORY.md entries, files not in index,
    broken [[wikilinks]], feedback/project entries missing Why/How,
    duplicate descriptions, MEMORY.md >200 lines.
  - run_audit(memory_root) is sub-millisecond on realistic input.

src/tick.rs
  - Runs audit::run_audit BEFORE deciding to spawn claude.
  - If total_issues == 0 → skip the spawn, log "audit clean — files=N ...",
    save ~30-80k tokens and ~30-60s wallclock per tick.
  - When the tick does run, the agent receives the audit JSON in the
    prompt so it never re-scans the directory.

cmmd audit / mmctl audit
  - New subcommands. Sub-second, no claude call, no quota cost.
  - --json for machine-readable output.
  - On real ~/.claude/projects/-home-deadpool/memory/ today: 4 issues
    (3 broken wikilinks, 1 feedback missing Why/How).

Verified
  - cargo test --lib: 20/20 passing (8 new audit tests + 12 existing)
  - cargo clippy --bins -- -D warnings: clean
  - cmmd audit against test-fixtures/memory: catches missing
    frontmatter + dangling MEMORY.md entry as expected
