typecheck-tests is at 155 errors / 48 files and growing — fix the ServiceToken shape and put it in CI

[sroussey]

The script is not in CI and the documented count is three measurements stale.

when	errors
CLAUDE.md (as written)	122
PR #311, 2026-08-20	140
dd11d316, today	155 across 48 files

bun run build and bun run test both pass over these files, so nothing else type-checks them — which is exactly the condition CLAUDE.md describes and then does not act on.

Dominant shape (~40 of the 48 files, all src/cli/queries/*.test.ts): a test helper hands ServiceToken<CrowdfundingRepositoryStorage> where an ITabularStorage is expected, so every .put() on it errors. One helper fix should clear the bulk.

Others worth separating out:

• DbStatus.test.ts:143 passes an updateProgress mock returning number where void | Promise<void> is required.
• A spac_candidate fixture omits the signal_filed_sic_6770 column added last window — a real near-miss, not a typing artifact.

Plan:

1. fix the helper;
2. sweep the remainder;
3. add bun run typecheck-tests to test.yml between format-check and build;
4. update the CLAUDE.md paragraph to say it is in CI, rather than describing the conditions under which it would be.
