Merge remote-tracking branch 'origin/main' into fix/391-browser-flakes

* ci: pin black and flake8, let the bandit hook fail, cache npm in the JS job (#352)

The lint job installs black==26.10.1 and flake8==7.4.1 from
requirements-dev.txt (the versions CI resolved on main today), so a new
release cannot turn CI red with no code change.

The local bandit hook ran 'bash -c ... "$@"; true': it could never
fail, and bash bound the first staged file to $0 so it was never
scanned. It now runs 'bandit -lll -q' directly, failing on high
severity exactly like code-quality.yml.

The frontend modules job's setup-node caches npm keyed on
tools/vendor/package-lock.json.

* test(history): wait on the writer's state, not short wall-clock pauses (#352)

Four 0.08 s pauses before asserting that the worker had not probed yet
now wait until the idle worker has run a whole loop pass at the current
manual clock value (three clock reads), so a slow runner cannot end the
pause before the worker decides. A mutation that probes 20 ms early now
fails two tests deterministically.

The real-clock bounded close no longer asserts close(0.02) returned in
under 0.2 s wall time; it asserts the in-flight write is still blocked
and the worker alive, like the output writer test. The manual-clock
bound stays exact. The last 0.1 s non-blocking submit check uses the
1 s NON_BLOCKING_CEILING from #351.

* test(api): give each API fixture database its own temp folder (#346)

Every PromptManagerAPI sweeps its database's folder at startup for the
stages, uploads and safety-backup copies an interrupted restore left.
The API test fixtures created their database directly in the system
temp folder, so any other test process starting an API there (another
worktree's suite, a pre-push hook, an agent's targeted run) deleted
this process's in-flight restore files. The restore, epoch and
retirement tests then failed with 'staged restore changed', 'unable to
open database file' or 503 instead of 409. Busy machines fail because
they are running other suites, not because they are slow: the same
CPU load with a private TMPDIR passes.

private_temp_db() puts the fixture database in a new folder removed at
cleanup (with any safety backups a restore left beside it). A
regression test sweeps a stand-in shared folder in the middle of a
multipart restore, as another suite's startup would.

* test(history): count worker parks, hold saturation blocks until released (#352)

wait_for_worker_pass now counts the idle worker's parks on its wake
event (two parks from now = one whole pass begun after the call)
instead of assuming a fixed number of clock reads per pass, which a
future clock read would have made vacuous. The real-clock bounded
close keeps a loose upper bound (0.02 s + NON_BLOCKING_CEILING).

The two saturation tests (history and output writer) blocked the
worker with release.wait(3) while they queued 1023 more items. On a
loaded runner the fill took longer than 3 s, the worker unblocked on
its own and drained part of the queue (pending 868..1017 != 1024),
and cleanup then reported a leaked worker. The block now holds until
the test releases it; 60 s is only a hang guard, and cleanup always
sets the release. Under one core with 8 busy loops: 8/8 runs failed
before, 6/6 pass after.

* test(maintenance): wait on duplicate jobs with a disk-bound hang guard (#409)

On Windows py3.13 CI (PR #405) a one-file duplicate cleanup missed its
10 s WAIT. The test already waits on the job's own task; the 10 s bound
acted as a deadline on disk-bound work. In the same 50 s window the
following tests' setups took up to 9 s against 0.1-0.6 s around it
while the test bodies stayed fast, which is consistent with a
process-wide disk I/O stall on the runner rather than a lease, handle,
executor or job stall (the log has no thread dump to show more).

tests/disk_waits.py holds the one disk-bound hang guard (90 s per wait,
under the 120 s per-test watchdog), shared with RESTORE_SECONDS (#382).
Waits on find and cleanup job tasks in the duplicate-files tests use
it; gates and server-state polls keep WAIT. The keeper-validation test
turns the safety backup off, since it does not test backups.
