fix(crux): clear crux type errors and make the crux typecheck blocking

[OAGr]

The crux typecheck has been advisory with 17 real errors. Its "baseline" file (crux/validate/crux-tsc-baseline.txt, bumped ~50 times) has not been read by anything since QUA-524 deleted the validator that used it. This PR fixes all 17 errors and makes the typecheck-crux gate step blocking (QUA-636).

• 16 type-only fixes:
  • Add 4 missing @wiki-server/*-route path aliases to crux/tsconfig.json (copied from apps/web/tsconfig.json).
  • Add crux/next-fetch.d.ts for Next's fetch(…, { next }) option.
  • Type exec options in crux/lib/aiid/fetch.ts.
  • Remove an always-true error !== 'not_found' comparison in crux/commands/agents.ts.
  • Test annotations in mutex.test.ts and lifecycle.test.ts.
• One real bug: ENTITY_REF_FK_MAP in crux/commands/tb-importers/propose-client.ts had no entry for publication or organization-fact. The semantic-scholar, openalex, crossref and wikidata T1 importers emit those, so buildProposeRequest crashed with "is not iterable". The server's /api/enrichment/propose does not accept those record types at all (SUPPORTED_RECORD_TYPES = grants, personnel, funding-rounds, benchmark-results), so guessing an FK mapping would only move the failure. buildProposeRequest now refuses them with a clear error naming the supported types. New tests cover both types and a supported one.
• Deletes the dead baseline file, drops advisory: true from typecheck-crux, and removes the "known baseline" exception from error-handling.md and validation-gate-system.md.

Verified: tsc --noEmit -p crux/tsconfig.json reports 0 errors; crux/commands/tb-importers tests 351/351; pre-push gate passed.

Protected Paths Check is red only because this PR touches protected files (crux/validate/validate-gate.ts, .claude/rules/error-handling.md, the baseline file, propose-client.ts). It's the repo's human-review gate, not a code failure: a maintainer needs to review and add gate:rules-ok. No code change will clear it, and I'm not adding the label myself.
