- remote_browser_targets(), _auto_route_remote(), active_browser_targets()
now accept and forward the key parameter so pubkey auth works during
the initial browser-cli.targets discovery call
- _multi_browser_targets() in tabs/groups/windows/session commands now
reads key from ctx.obj and passes it through
- send_command() auto-saves the key spec (e.g. "agent") to remotes.json
on first explicit use; subsequent calls to the same remote reuse it
without requiring --key every time
- Added save_remote_key() / key_for_remote() helpers (mirrors token helpers)
