test: guard rig convention docs drift

[zerone0x]

What & why

Adds a mechanical drift guard for the Rig Doctor convention list.

Closes #114

The test reads the recognised rig conventions table from docs/rig-doctor.md and compares its convention labels to the detector's exported CONVENTIONS list. It also asserts every implemented convention has non-empty user-facing evidence text.

Type of change

• Feature
• Improvement
• Fix
• Docs
• Infra / chore (no user-visible effect)

Definition of done

• Code is fully wired and reachable by the user — no dead paths, stubs, TODOs, or commented-out code.
• No mocks, fake data, or placeholder values — real APIs and real data only.
• Every interactive element has hover, active, and focus states (UI changes).
• Loading, empty, and error states are designed and helpful (UI changes).
• npm test passes and npm run typecheck is clean.
• npm run lint is clean (or only pre-existing warnings).
• I reviewed my own git diff — every changed line is justified.

Verification

• npx vitest run tests/rig-report.test.js — 22 tests passed.
• Drift proof: temporarily removed the Mixamo row from docs/rig-doctor.md; npx vitest run tests/rig-report.test.js failed with expected [ 'Ready Player Me', …(10) ] to deeply equal [ 'Ready Player Me', 'Mixamo', …(10) ]; restored the row and reran the focused suite successfully.
• npm run typecheck currently fails on unrelated existing errors in api/_lib/brownout/provenance.js, api/_lib/ops/x402-settle-health.js, api/_lib/sniper-solvency.js, and api/_lib/upstream-fetch.js.
• npm run lint -- --quiet currently fails on unrelated existing errors in packages/metaplex-agent-mcp/docs/app.js and src/categories.js.

Changelog

• Added a data/changelog.json entry, or this change is internal-only and needs none.
