v0.1.5

Added

• Per-share atomic publish-on-close (publish_on_close, default false).
  New files on shares with the option enabled are written under a hidden
  temp name (.rssmb-tmp.<final-name>.<8 hex>, same directory) and atomically
  renamed to the final name when the last SMB handle closes. SMB clients
  observe the final name throughout (CREATE by name, QUERY_DIRECTORY,
  QUERY_INFO, rename, delete, CHANGE_NOTIFY, case-insensitive lookup all go
  through a single VFS resolution hook); only the backing filesystem sees the
  temp name. Fixes host-side consumers (watchers, ingest pipelines, backups)
  reading a pre-sized file with zero data while a client is still writing.
  Covers CREATE / OPEN_IF-when-creating / OVERWRITE_IF / SUPERSEDE on regular
  files; plain OPEN of an existing file is untouched (deliberate). Durable
  handles carry the pending entry (reconnect resumes it; durable expiry
  publishes as a close). Crash orphans (.rssmb-tmp.*, no map entry, older
  than 1 h) are removed at share startup and by a 10-minute sweep in the
  server sweeper.
