Pro profiles: capture after Firefox lets go of the profile

[JWriter20]

Closing a Pro profile's browser never synced its state. Both sessions of FlashCollection's live test logged:

camoufox-pro: profile prf_…'s state was not synced (prefs.js changed size after capture)
camoufox-pro: profile prf_…'s state was not synced (places.sqlite changed size after capture)

attachLease(lease, context, "close") starts the sync on the persistent context's close event, which Playwright emits while Firefox is still flushing those files during shutdown. The capture read them mid-write, the size check rightly refused it, and the session was parked in pending/.

onClose now waits for Firefox to release the profile before capturing: on Linux/macOS until the process named by the lock symlink (<address>:+<pid>) has exited, on Windows until parent.lock can be opened. A stale lock from a crash is ignored. If it times out (30 s) the size check still refuses a moving file and the session is kept for the next launch, as before.

Tests: the wait lasts exactly until a real lock-holding process exits; a stale or absent lock returns at once. Full TS suite 822 passed, biome and tsc clean. The Windows branch is not exercised by CI here.

_{The Playwright suite is upstream playwright-python at the tag above, fetched fresh, with tests/camoufox/ overlaid. It runs with world isolation on — the configuration Camoufox ships — and only the failures are re-run with it off; those count as passes and are reported above as main-world fallbacks, which is the size of the isolated-world gap. Tests Camoufox cannot pass by design are deselected via ci/skiplist.yml — each with a stated reason. The stealth check reports a grade only; its per-vector detail is deliberately never published.}
