Duncan 1d3c27c676 fix(desktop): harden blob lockfile against tmp-cleaner unlink race
The service-keyed /tmp blob lockfile could be unlinked by a tmp cleaner
while a holder kept its flock; a recreate under the same pathname is a
fresh inode a second process can lock in parallel, splitting mutual
exclusion across two inodes. Recheck (dev, ino) after the lock is granted
and re-acquire against the live pathname on a mismatch, bounded by
MAX_BLOB_LOCK_REACQUIRE so a pathname churned faster than we can lock
fails loudly instead of spinning.
