feat(gamepad): controller discovery + client-negotiated pad type + rich DualSense end to end
The Apple client grows full gamepad support and punktfunk/1 learns to negotiate the virtual pad type: - Protocol: Hello carries a GamepadPref byte (offset 21, the same trailing-byte back-compat pattern as the compositor; echoed resolved in Welcome at 54). Host precedence: explicit client choice > PUNKTFUNK_GAMEPAD env > Xbox 360, DualSense (UHID) only where available. ABI: punktfunk_connect_ex2 + punktfunk_connection_gamepad (connect_ex delegates; ABI_VERSION stays 2 — the trailing byte IS the compat mechanism). punktfunk-client-rs gets --gamepad. - Swift client: GamepadManager (app-lifetime discovery + selection — Settings lists every controller with capabilities/battery/"In use"; exactly ONE pad forwards as pad 0, auto = most recently connected, or pinned), GamepadCapture (snapshot-diff button/axis events, DualSense touchpad + ~250 Hz motion on the rich-input plane, held state released on switch/deactivate/stop), GamepadFeedback (rumble → CoreHaptics per-handle engines; lightbar → GCDeviceLight; player LEDs → playerIndex; adaptive-trigger blocks → the table-driven DualSenseTriggerEffect parser → GCDualSenseAdaptiveTrigger, exact for the 10-zone positional modes). The pad type auto-resolves from the physical controller at connect time, user-overridable in Settings. - Host DualSense fixes surfaced by adversarial review against hid-playstation / SDL / Nielk1 ground truth: input-report sensor/touch offsets were off by one (the kernel read garbage motion + phantom touches), the L2/R2 trigger blocks were swapped (the report is right-trigger-first), feedback now gates on the report's valid-flags (a plain rumble write no longer blanks lightbar/ triggers), and the touchpad rescale clamps to the advertised ABS_MT extents. - Tests: Hello/Welcome trailing-byte back-compat, pick_gamepad precedence, byte-exact input-report layout, valid-flag gating, per-mode trigger-parser table (incl. packed 3-bit zones), wire conversions, and a scripted loopback feedback burst (PUNKTFUNK_TEST_FEEDBACK=1) asserted through the xcframework on the rumble + HID-output planes. Validated: cargo test/clippy/fmt green on macOS + Linux (61 host tests), swift build/test green, test-loopback.sh green, tvOS/iOS targets compile. DualSense motion sign/scale is derived from the calibration blob, not yet live-verified (constants isolated in GamepadWire). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
