Closes CL-11849 (https://linear.app/abklabs/issue/CL-11849/shorten-agentsmd-to-the-conventions-no-check-enforces).

Changes

AGENTS.md now points to the check and the Triage policy, and keeps only conventions they don't fully enforce.

• Removed, because a check enforces them:
  • exact dependency pins (pins:verify)
  • importing Interchange by path (the architecture test and Triage's errors-kept rule)
  • the vendor manifest check (vendor:verify)
  • the list of what bun run check runs
• Kept, because they're only partly enforced: Conventional Commits and one logical change per commit and pull request. The commit hook is opt-in, and Triage only labels.

Verification

• A separate check matched every removed rule to its enforcing script, test or Triage rule, and every link resolves.
• Format passes.
