Adds the public extension points the velxio-prod overlay uses to bind
real canvas-side I2C/SPI/UART models (BME280, future MCP23017, etc.)
to a running Pi guest's protocol shims:
- qemu_manager: set_pi_slave_handler(fn) / get_pi_slave_handler() for
pi_attach_slave + pi_detach_slave WebSocket messages. OSS image
leaves the hook unset so the messages are silently dropped.
- simulation route: parses the two new WS message types and forwards
them to the registered handler when present.
- RaspberryPi3Bridge: attachSlave(spec) / detachSlave(spec) frontend
side of the protocol.
- piSlaveScanner: at simulation start walks components + wires,
identifies I2C/SPI/UART peers wired to Pi protocol pins (40-pin
header physical-pin numbering), and emits one attach per
bus/address pair (deduped across SDA+SCL wires).
- RaspberryPiWorkspace: invokes the scanner once the bridge is open,
with retries to ride out the WS-still-connecting race.
- integration test: pi3_bme280_attach.py boots the Pi, pre-attaches a
BME280 via the slave handler, runs a host-side proto loop, runs
guest python smbus2.read_byte_data(0x76, 0xD0) and asserts the
console reads back CHIP=0x60.

PiTerminal didn't call term.focus() on mount, so xterm.js stayed
passive — onData only fires when the DOM element has focus. Users
saw the boot prompt but their keystrokes went to whatever element
held focus when they clicked Run (canvas, code editor), never
reaching the bridge. Calling focus() right after fit() makes the
prompt receive input the moment it's visible.
The qemu_manager change adds INFO-level logging when serial_input
WebSocket messages reach send_serial_bytes — useful diagnostic for
future Pi3 input problems (proves whether bytes reached the backend
before we look at TTY / kernel / PL011 wiring).
