crdt-sync 0.9.2: per-write temp file for the Firebase credential cache
**FileCredentialStore.save wrote every save through one fixed `<cache>.tmp`.**
Two processes share a credential cache (a long-running stream and a periodic
sync), so one could rename the other's half-written temp file into place and
leave a truncated refresh token behind. Each save now gets its own mkstemp
file in the same directory -- created 0600 from the outset, so the token is
never world-readable -- and replaces the cache atomically. A failed write
unlinks its temp file and leaves the previous cache untouched.

Tests cover: no temp file left after a save, distinct temp names per write,
and an interrupted write keeping the old credentials with no leaked temp.
