Merged

`test/credentials.test.ts` now runs in about 2.2 s instead of 7.25 s, and its slowest test takes 0.63 s instead of 5.58 s. The same 6 tests and 54 assertions still pass, and none are skipped or deleted.

test/credentials.test.ts now runs in about 2.2 s instead of 7.25 s, and its slowest test takes 0.63 s instead of 5.58 s. The same 6 tests and 54 assertions still pass, and none are skipped or deleted.

Before and after (bun test test/credentials.test.ts, crew sandbox):

Before, on main 821389cdc: 6 pass, 7.25 s for the file. The slow test was "a crew run on the platform's token > is counted under platform (env), moving while it runs", at 5.58 s when #1335 measured it.
After: 6 pass, 2.11 s, 2.19 s and 2.21 s over three runs. Per-test times from the junit report were 0.63 s for that test, 0.06 s for the board test, and under 5 ms for each of the rest.

Why the slow test was slow: after the issue was assigned, the run sat in the queue until the crew pump's next tick, which is 5 s by default. Nothing in the test needed that wait.

What changed (only test/credentials.test.ts):

startCrew is given tickMs: 20, so the queued run starts at once. test/usage.test.ts does the same since #10230.
The until poll sleeps 10 ms instead of 50 ms.
The fake claude's hold loop sleeps 20 ms instead of 100 ms, so no sleep over 50 ms remains.
Each test now opens with a one-line // Invariant: comment. All six prove different things, so none was removed.
Setup was already built once per file: one forge, one crew, one fake binary, all in beforeAll.

Shown to fail without the code it guards: the only test whose behaviour changed is the platform-token run. With the usage.delta append in src/crew/runner.ts disabled, it fails in 318 ms (Expected - 3 / Received + 1 on the mid-run outbox check). It passes again with the code restored.

bun scripts/gate.ts and bun x tsc --noEmit both pass.

Test-only change, matches the pattern #10230 set in usage.test.ts: tickMs 20 so the queued run starts at once, shorter polls, the fake binary hold loop at 20 ms, and a one-line invariant atop each of the six tests. The option exists (src/crew/runner.ts tickMs). No behaviour or product code is touched; no README, dependency or security surface involved. I could not check out the head in my sandbox (the base runs 7.2 s here), so the 2.2 s figure is the builder's, not mine. Next: (1) the Bun.sleep(10) poll in until() could be event-driven rather than polled; (2) keep an eye on the 20 ms tick under a loaded gate, since the file only has a 10 s budget and no margin test.
