G5: buttonMask mapped the dedicated share/create/capture element onto BTN_BACK,
the same bit as View (buttonOptions). On an Xbox-Series pad those are two
distinct physical buttons, so Share was indistinguishable from View on the
host and never delivered the capture bit the host already decodes (DualSense
mute / Steam quick-access). Route it to BTN_MISC1 instead, matching the Rust
client's `Button::Misc1 => wire::BTN_MISC1`. Adds `misc1` to GamepadWire and
allButtons so a held capture button is released on flush like the others.
(On-glass verify owed on a real Xbox-Series pad; a clone pad that exposes one
button as both buttonOptions and Share now emits back+misc1 for it — harmless
on a plain xpad session and rare otherwise.)
G22 (partial): define paddle1..4 for wire completeness, but leave them out of
buttonMask/allButtons until the GameController paddleButton1..4 ↔ BTN_PADDLE
physical correspondence is confirmed on a real Elite pad.
G15: replace the 3-bit spot-check with an exhaustive assertion of every
GamepadWire button/axis constant against the generated C ABI header
(punktfunk_core.h), so any Swift-side drift from punktfunk_core::input::gamepad
fails CI.
swift build + full PunktfunkKit suite green (124 passed, 5 skipped).
