fix(quality): drain v3.8.50 base-reds — doc counts + orphan uncloseai test

[yourspraveen]

Drains two HARD failures that have been red on release/v3.8.50 for every PR targeting it. Reported on #9985; neither belongs to the PRs that tripped over them.

1. check:docs-counts — job Docs Gates (fast-path)

Three counts drifted when code landed without the matching doc update:

Claim	Docs said	Code has	Origin
DB migrations	157	159	84c9dfdd2 (#11103) → 161_config_audit_log.sql; aa1287368 (#11118/#11123) → 162_remove_hackclub_provider.sql
free-forever providers	57	56	aa1287368 (#11118/#11123) — Hack Club AI removed
free-tier provider pools	41	40	same

The migration count lives in README.md, AGENTS.md and llm.txt, and llm.txt is mirrored into 42 locales under docs/i18n/<locale>/llm.txt. check:docs-sync requires the mirrors to match the root, so all 45 files move together — that is why the diff is wide but shallow (one number per file). The free-forever and pool counts are hand-maintained numbers baked into README.md and two SVGs (promise-pillars, free-tier-budget), including their alt/desc text, so those were updated in place.

2. check:test-discovery — job Fast Quality Gates

✗ [órfão NOVO] tests/unit/providers/uncloseai-noauth.test.ts — nenhum runner coleta este arquivo (ele NUNCA roda).

tests/unit/providers/uncloseai-noauth.test.ts was the only file under tests/unit/providers/, and providers is absent from the collected-directory list in test:unit / test:unit:ci:shard:

tests/unit/{api,auth,authz,build,cli,cli-helper,combo,compression,correctness,cors,db,db-adapters,
docs,gamification,guardrails,lib,mcp,memory,runtime,security,settings,shared,services,ui,usage}

So it has never executed since landing in d61eec63b (#8864/#11064). The gate failure is the smaller problem — the real cost is that the UncloseAI no-auth regression it guards has been unprotected this whole time.

Moved to tests/unit/providers-uncloseai-noauth.test.ts, matching the existing root-level convention (providers-page-utils, providers-validate-route, providers-route-managed-catalog, …). It imports only through the @/ alias, so directory depth is irrelevant, and it passes now that it actually runs. Widening the runner glob instead was the alternative, but that changes shard composition for a directory holding one file.

Verification

Gate	Before	After
check:docs-counts	3 STRICT drifts	exit 0
check:docs-all	fail	exit 0
check:docs-sync (42 locale mirrors)	pass	pass
check:test-discovery	1 orphan	exit 0
check:mutation-test-coverage	pass	pass (no drift; test still listed)
tests/unit/providers-uncloseai-noauth.test.ts	never ran	1 pass

No production code changes — docs counts plus one test-file move.
