The unpushed-commit detector's author check was existential: any bot-authored
commit in origin/<branch>..HEAD armed a push of HEAD, silently publishing
interleaved user-authored commits in ~/.gstack. Now the gate requires the
author-scoped count to equal the total unpushed count — one user commit
disables the autonomous retry entirely (user commits still ride along when a
real drain pushes). Detached HEAD is excluded (origin/HEAD usually resolves,
making the retry a 10-minutely doomed push).
The lock-release trap now installs immediately after lock acquisition instead
of after the empty-queue fast path — the steady state at every skill boundary
leaked the lock dir and relied on stale-PID detection, which PID reuse defeats.
An INT during the detector's network push is covered too.
Matrix test: interleaved user commit blocks the detector, then a real drain
delivers everything.
