AI coding agents read AGENTS.md automatically, not README. Make AGENTS.md
a thin pointer: the stable first-action facts plus links to CONTRIBUTING.md,
README.md, and package.json#scripts. Keep the rules prose in CONTRIBUTING.md
so humans and agents don't diverge (same anti-drift move as dropping
project-specs.md).
Clarify the agent's verification loop: npm run test is the mandatory gate;
the pre-commit hook already runs the fast offline checks (tsc, oxlint, oxfmt,
cspell) on staged files, and npm run check (knip + outdated) is repo-maintenance,
not part of the feature loop. Forbid type-system escape hatches (@ts-nocheck,
oxlint-disable, as-casts) as agent-only rules; a human may still add a
review-visible disable as a last resort, so the location convention stays in
CONTRIBUTING.md with a forward reference.
