Jeroen UbbinkandClaude Opus 4.8 c2a2d76eae fix(vault): harden the auto-generated master key file
Three fixes to how a node provisions its own master key when the operator
sets no ROUTSTR_SECRET_KEY:

- Publish the key atomically. It is written to a same-directory temp file,
  fsynced, then os.link-ed into place and the directory fsynced. os.link
  publishes the complete file in one step, so a crash mid-write can no longer
  strand an empty key at the final path that a later boot would read as corrupt
  and then fail to decrypt every secret under. os.link also refuses to clobber,
  so a racing worker that generated first keeps ownership and the loser adopts
  its key.
- Tighten loose permissions on read. A key file that is group/other-readable is
  repaired to 0600 rather than trusted, keeping an upgrading node booting.
- Stop printing the key value. The one-time notice names the file to back up and
  shouts the backup imperative, but no longer echoes the key itself, which would
  leak it into captured stdout / aggregated container logs; the durable 0600 file
  is the recovery path.
