leora 6e86aeb2af Fix R5: SealedStore plaintext tmp is 0600 with fsync/cleanup
Plaintext working copy and export backup were creatable world-readable
under a 0700 temp dir. Write via os.open(mode=0600), fsync, unlink on
failure; pin temp dir 0700; remove export after flush. Document SQLCipher
as deferred — seal-on is not an encrypted DB while the process is open.
