daemon: relocate any non-.md file that lands in /vault to matching /data path

/vault is notes-only by design; binaries saved there by hand, by an
agent, or by a sync client now get moved to /data automatically
instead of sitting in the wrong tree. Wired into live inotify (file
create + file move) and the periodic reconcile sweep so pre-existing
drift self-heals too. Leaves the vault copy in place with a warning
ntfy if a same-named file already exists at the /data destination.
