The managed runner is de-privileged on Windows now (runs as LocalService),
and %ProgramData%\punktfunk is locked read-only to it — so writing config/
cache straight under the config dir fails EPERM (proven on-glass). Move the
plugin's state to <config_dir>/plugin-state/rom-manager, which
`punktfunk-host plugins enable` grants the runner write on. On Linux the
runner owns the config dir, so the path is writable there too — one path, no
branch.
Migrate a pre-0.2.1 config/cache from the old <config_dir>/rom-manager on
first load (copy, guarded, best-effort) so an existing operator's roots +
launch templates survive the move instead of silently resetting to defaults.
