Open an aindrive drive as a read-only folder in Memona

The plugin reaches a drive through aindrive's remote MCP endpoint with
the drive's access token. Opening a connection asks which tools the
token may call, so it works while the drive's machine sleeps. Listing,
stat and reading map to list_files, stat and read_file; a read is
statted first, and a file whose length changed in between is refused as
a conflict. Reads decode only the window asked for, straight from the
reply pieces, so any 1 MiB slice of a file up to aindrive's 8 MiB limit
fits Memona's per-call fuel.
