[AI] Add comprehensive coverage for the migration runner and view setup

Lays down the test surface ahead of the fix for #7710. New tests assert
behavior the migration code should have but doesn't yet — three of them
are introduced as `test.skip` TDD placeholders so they fail loudly to
re-enable once the follow-up PR lands:

- `withMigrationsDir` restores the previous dir when its callback throws
  (today it leaks the override into the rest of the suite).
- `probeViews` raises `schema-out-of-sync: <viewName>` when an
  underlying table/column is missing.
- `probeViews` error message carries the failing view name and cause so
  the budget-load funnel can surface a recoverable error to the user.

Also includes new regression coverage that passes against current
master: pure-helper tests for `getUpMigration` / `getPending`, numeric
(non-lexical) sort + extension filter in `getMigrationList`, end-to-end
`migrate` against `fs.migrationsPath` with column-presence assertions
(both JS and SQL migrations), `applyMigration` SQL error propagation,
`patchBadMigrations` both branches, `checkDatabaseValidity` length
branch, and `updateViews` hash-mismatch recreation + no-op-on-match
behavior.

Test-infrastructure fix: the `migrate` mock in `mocks/setup.ts` now
preserves the real return value (and resets the uuid seed in a
`finally`), which several of the new assertions rely on.
