The Windows DualSense and DualShock 4 managers passed the raw wire
buttons straight into `DsState::from_gamepad`, so a client's Steam back
grips (BTN_PADDLE1..4) were silently dropped and `PUNKTFUNK_STEAM_REMAP`
was ignored — the Linux DS/DS4 backends already fold them via
`steam_remap::fold_paddles`. Bring the Windows backends to parity: add a
`remap: steam_remap::RemapConfig` field (`::from_env()` in `new()`) to
both managers and fold the paddles before `from_gamepad`, exactly as
`linux/dualsense.rs` / `linux/dualshock4.rs`. Default policy stays Drop
(don't fire buttons the user didn't ask for); set the env to map the
grips onto stick-clicks or shoulders.
`steam_remap` was gated `target_os = "linux"`; widened to
`any(linux, windows)`. It's pure (only punktfunk_core + std::env); its
Linux-only Deck motion rescale is `pub` so it compiles clean on Windows
with no dead-code warning.
Verified: Linux .21 (clippy -D warnings clean, inject tests 32 pass / 0
fail — the gate widening is a no-op there); Windows .173 (clean-recheck
of punktfunk-host, cargo clippy --all-targets -D warnings EXITCODE 0,
steam_remap + both managers compiling on Windows for the first time).
On-glass with a real DualSense/DS4 + PUNKTFUNK_STEAM_REMAP still owed.
