tui: --open PATH to create/attach a session for an arbitrary binary

- app: when open_path is set, idb_open (idle_ttl=1e9, long timeout) and pin the
  returned session; clean status on failure (e.g. non-writable dir)
- tui.py: --open flag + usage docs (attach vs open)
- verified: --open targets/cat -> new session, 161 funcs loaded
