* fix(#474): route state date-stamping + installer lock loop through clock seam (nowIso/today + GSD_NOW_MS adapter)

* fix(#474): use process.ppid (not pid 1) as held-lock owner in install-lock timeout test
pid 1 is POSIX init/launchd (always alive) but does not exist on Windows,
so isPidAlive(1) returns false, the lock is reclaimed as stale, and
acquireInstallMigrationLock no longer throws -- failing the timeout
assertion on windows-latest,22. process.ppid is a live, non-self process
on every platform, so the lock is seen as held and the timeout path
throws deterministically cross-platform.
