feat: add no-mistakes-config rule for path, glob, and limit lints

[jonathanong]

Summary

• Add opt-in no-mistakes-config filesystem rule for the loaded .no-mistakes.yml.
• Lint missing project/test path refs, empty include/exclude globs, and env-level limit combined with a direct group.

Test plan

• Fixtures: missing-path, empty-glob, env-limit, pass
• CI green

• rustfmt filesystem_dispatch, split paths.rs under 200 lines, and clippy from_ref on glob lint.
• P1: registered no-mistakes-config in check_tasks FILESYSTEM_RULE_IDS; omitted groups now count as implicit Direct; empty limit objects are ignored. P2 tracked-inventory/external-root/negation/literal-globs/config-path/extra-test-paths deferred as follow-ups for this opt-in v1.
• Treat root: . as present. Remaining P2s (project-relative glob matching, trigger ?/[] syntax, file-as-directory) deferred for v1.
• Skip Direct-limit warning when env.all is true; remaining P2s (test-plan globs vs discovered tests, skip disabled rule applications, unused SourceStore) deferred for this opt-in v1. codecov/project/rust no-head is a race with the rust coverage job.
• P2 Playwright per-app roots and unused SourceStore deferred for v1. Coverage fail is inherited from main perf: share source Arcs, intern borrowed paths, and serialize JSON once #756.
• Merged origin/main (feat: add postgres-no-offset check rule #758 postgres-no-offset) and kept both no-mistakes-config and postgres-no-offset dispatch registrations. Coverage fail remains inherited from perf: share source Arcs, intern borrowed paths, and serialize JSON once #756.
• Codex usage-limit comment only; CI still in progress after main merge. No code change.
• codecov/project/rust no-head while Rust tests and coverage is still in progress; no code change.
• Merged origin/main after feat: camelCase-only TestPlan Node API with includeGlob #764 (postgres-require-query-annotation). Deferred P2 percent-100 limits and reactTraits.frontendRoot as v1 follow-ups.
• Codex usage-limit comment only; CI in progress after merging main. No code change.
• First-look only; CI restarted after feat: add workflow-topology-policy rule and step-order helpers #763 squash-merged into this branch. No code change this tick.
• Codex usage-limit comment only; codecov no-head while rust coverage is in progress. No code change.
• Defer Codex P2s (reusable-workflow uses, policy finding file paths, request-scoped topology snapshot, empty step selectors) as v1 follow-ups; codecov/project/rust no-head while rust coverage is still in progress. No code change.
• Codex usage-limit comment only; merged feat: add --profile ci and memoize ciTopology in-process #765/feat: add postgres-no-add-column check rule #767 from main. No code change.
• codecov/project/rust no-head while rust coverage is still in progress. No code change.
• Defer Codex P2 ordered-step suffix search as a v1 follow-up. Rebase onto main after test: raise Rust coverage gates to 99.5% #759/fix: report unnamed packages when requireNamedPackage is true #760/feat(postgres): honor DROP INDEX and peel chr()-encoded SQL #762.
• Merged feat: add postgres-require-named-constraints check rule #768 from main; restored dropped filesystem_dispatch constants. Cancelled stale CI is superseded by the new push.
• Codex usage-limit comment only. No code change.
• Defer Codex P2 collecting ci/infra path fields as a v1 follow-up. Rust coverage failed at 98.26% lines vs the 99.5% gate from test: raise Rust coverage gates to 99.5% #759; 761-specific holes are workflow_topology_policy evaluate* (not copying test: raise Rust coverage gates to 99.5% #759 tests onto this PR). CodSpeed regression treated as noise. No code change this tick.
• Added topology-policy graph/inventory/step-order tests; merged feat: add postgres-require-fk-on-delete check rule #769. Coverage holes were in 761-owned evaluate* modules.
• Rust line coverage still 98.36% vs 99.5% gate (functions are 99.50%). Remaining holes are crate-wide, not only topology-policy; not copying test: raise Rust coverage gates to 99.5% #759 tests. No further code change this tick.
• CodSpeed treated as noise; codecov/project/rust no-head follows rust coverage fail. Line coverage still below 99.5%; will keep iterating 761-owned holes without copying test: raise Rust coverage gates to 99.5% #759 tests. No push this tick.
• Codex usage-limit comments are noise; minimize and continue.
• codecov/project/rust "No coverage information found on head" is follow-on while Rust coverage is still running; no code change.
• add topology-policy evaluate coverage tests for codecov/patch/rust 92% vs 99% target; do not copy test: raise Rust coverage gates to 99.5% #759 crate-wide tests.
