* feat(#453): add deterministic clock seam to lock modules
Introduces get-shit-done/bin/lib/clock.cjs exporting realClock with
now() (Date.now) and sleep() (Atomics.wait). acquireStateLock,
writeStateMd, and readModifyWriteStateMd in state.cjs each accept an
optional trailing clock param (default: realClock). withPlanningLock in
planning-workspace.cjs gains the same seam. No production behavior
change — all callers that omit the param continue to use realClock.
Adds tests/helpers/clock.cjs (makeFakeClock) and tests/clock-seam.test.cjs
with 20 deterministic in-process tests covering: lock serialization,
timeout throw at maxWaitMs boundary, stale-lock takeover, lock released
on error path, withPlanningLock timeout recovery, exit-cleanup integration,
readModifyWriteStateMd call-site coverage (7 cmd*), and roadmap analyze
behavioral assertion (50 phases, no elapsed-time gate).
Deletes/converts per research verdicts: removes 11 source-grep/elapsed-time/
non-deterministic-concurrent tests across concurrency-safety.test.cjs,
locking-bugs-1909-1916-1925-1927.test.cjs, and bug-1974-context-exhaustion-
record.test.cjs. All deleted tests have deterministic replacements in
clock-seam.test.cjs or surviving barrier-based tests.

* fix(state): acquireStateLock retries on transient Docker/NFS errno codes
Expands retry allowlist to ENOENT/EINVAL/EIO/ESTALE/EAGAIN/EINTR in addition
to existing EPERM/EBUSY. Truly fatal codes (EMFILE/ENOSPC/EROFS/EACCES) still
throw. Resolves the locking-bugs regression seen across all 8 open
consolidation PRs (#3738, #3741, #3752, #3754, #3756, #3759, #3760, #3769).
Closes#3776

* fix(state): retry on EPERM/EBUSY in acquireStateLock and withPlanningLock
Resolves state update TOCTOU failure on macos-22 and config-set
concurrency failure on windows-24.
Root cause: openSync(O_CREAT|O_EXCL) can return EPERM or EBUSY
transiently on some CI OS+AV combinations when the lock file is
briefly held open by the deleting process; the new throw-on-non-EEXIST
guard from #3772 propagated these transient errors, killing child
processes and causing lost updates in the concurrency tests.
Fix: guard EPERM/EBUSY with an explicit continue before the
throw-on-non-EEXIST line in both acquireStateLock and withPlanningLock;
the C1 source-audit test still passes because the throw pattern is
preserved for all other non-EEXIST codes.
