fix: read/write the library via the host ingest inbox (de-privileged runner)

The host plugin runner is de-privileged now (LocalService) and can't read the
interactive user's %APPDATA%\Playnite\ExtensionsData — so it never saw the
export. Bridge it through the host's user-writable ingest inbox:

- exporter (C#): also drop punktfunk-library.json into
  %ProgramData%\punktfunk\ingest\playnite (best-effort, only when a punktfunk
  host is present), alongside its ExtensionsData home.
- plugin (TS): locateExport() reads <config_dir>/ingest/playnite first, then
  falls back to the ExtensionsData scan (same-user/SYSTEM runner, Linux). The
  watcher also watches the inbox so a drop reconciles within seconds.
