diegosouzapw b3f6f697ef test(infra): retry recursive temp-dir removal on main (main twin of #11968)
`main` has been red since b342c1a361 on the vitest and integration gates:

  ✖ tests/unit/autoCombo/provider-family-combos.test.ts > auto/<family>
  ✖ chat pipeline applies Codex OAuth fingerprint and priority tier inside combos

Both call resetStorage() from beforeEach, which does an fs.rmSync(TEST_DATA_DIR,
{recursive: true, force: true}) with no retry, and intermittently loses the race
with a not-yet-released SQLite handle (ENOTEMPTY).

release/v3.8.51 fixed this in #11968 with a mechanical codemod adding
maxRetries/retryDelay to every recursive rm/rmSync/rmdirSync under tests/, but
that PR landed only on the release branch. Because main only receives work at
the release squash, it stayed broken for the whole cycle — and repo-wide gates
then turn every open PR into main red on checks unrelated to their diff.

This is the --base main twin: re-runs the same codemod that already shipped on
the release branch (scripts/ad-hoc/codemod-rm-maxretries.mjs), so the two
branches converge on identical test-teardown semantics. Test-only; no product
logic is touched.

The remaining three failures reported on #12133 (unit full suite exceeding its
4800s ceiling, package-artifact exceeding 1200s, and the boot-smoke that is
skipped as a consequence) are runner-contention timeouts, not code defects —
validate-release-green.mjs runs those heavy gates concurrently on one shared
hosted runner. There is no fix to port for those.

// Test-only DATA_DIR isolation.
//
// Loaded via `node --import ./tests/_setup/isolateDataDir.ts` from the test/mutation
// invocations (package.json test scripts, stryker.conf.json tap.nodeArgs, the
// quality.yml TIA step, and the CI test jobs) — NEVER from production. It MUST stay
// out of open-sse/utils/setupPolyfill.ts, which is also imported by production
// (bin/omniroute.mjs, proxyFetch.ts, proxyDispatcher.ts) where redirecting DATA_DIR
// would point the live SQLite DB at a throwaway temp dir.
//
// Why: node:test spawns a process per test file and Stryker spawns one per sandbox,
// but every process resolves DATA_DIR to the SAME default (~/.omniroute) when the env
// var is unset (see src/lib/dataPaths.ts::resolveDataDir). Concurrent processes then
// open the SAME on-disk storage.sqlite, causing cross-file state races: SQLite lock
// contention that hangs `test:unit` under high `--test-concurrency`, and the
// non-deterministic baseline that forced Stryker to `concurrency: 1`.
//
// Giving each process its own DATA_DIR under the OS temp dir removes the shared file,
// so concurrent test processes never collide. Tests that set DATA_DIR explicitly keep
// winning — this only fills in an isolated default when none was chosen.
