Remove Remote feature and phpseclib dependency

- Remove Illuminate\Remote namespace (RemoteManager, Connection, Gateway, etc.)
- Remove SSH Facade
- Remove TailCommand (depends on Remote)
- Remove RemoteSecLibGatewayTest
- Remove phpseclib/phpseclib from dependencies (only used by Remote feature)
- Update Application.php to remove 'remote' service binding
- Update composer.json to remove phpseclib/phpseclib requirement and illuminate/remote from replace

All tests pass successfully after removal.
