#10 transport (obdcore/transport.py):
- TcpTransport.read raises IOError on a real socket error or peer-close instead
of swallowing it as a timeout, so a dead WiFi link surfaces (via the #8 poll
handler) as 'connection lost' rather than a frozen dashboard.
- TcpTransport.reset_input_buffer drains at most 64 chunks — never spins forever.
- BleTransport closes the client + stops the event-loop thread on connect
timeout (no leak), caps the notification buffer at 64 KiB, and close() is
robust when only partially initialised.
#11 controller (gui/controller.py, obdcore/store.py):
- connect() closes the transport and nulls the link if init()/connect() raises,
so a failed/retried connect doesn't orphan sockets/threads.
- stop_record() unhooks store.recorder BEFORE closing it, and CsvRecorder now
has a 'closed' guard so a poll-thread write racing close() is a no-op instead
of an I/O-on-closed-file crash.

- obdcore/transport.py: pluggable byte transports -- SerialTransport,
TcpTransport (WiFi ELM327, stdlib socket), BleTransport (experimental, via
optional 'bleak'; background asyncio loop buffering notifications). ble_scan().
- ElmLink refactored onto a transport with .serial()/.tcp()/.ble() factories
(close/cmd now go through self.io); no behavior change for serial.
- Controller.connect(conn={kind:serial|wifi|ble,...}); GUI connection bar gains
a transport selector (Serial/USB/BT-SPP | WiFi host:port | Bluetooth LE + Scan).
- Classic-Bluetooth needs no new code (pairs as a serial port); WiFi needs no
extra deps; BLE is opt-in (bleak not bundled, so CI binaries keep building).
- tests/test_transport.py: drives ElmLink over a fake ELM TCP server end-to-end
(connect, RPM, readiness, VIN). All suites pass.
