Add per-trigger input modes in mapping mode: Hair Trigger presses/releases on short pull reversals; two-stage pulls assign separate soft/full buttons; Hip Fire delays the soft action so a fast full pull can bypass it. Thresholds, hysteresis, delay, assignments and exclusive full-pull behavior are editable with live raw/output meters.

Synthesized buttons pass through existing keyboard/gamepad assignments. Native gamepad input is preserved. The timer-driven pipeline releases stage actions and settles delayed Hip Fire output even when no further HID report arrives.

Dependencies and focused review

Stacked PR 4/7; depends on #12 and the earlier layers, starting with #9. All targets are upstream main, so GitHub's Files changed view currently includes unmerged dependencies. Review only this feature's incremental diff (commit 5c1c798).

Merge in the order below. Preserve the shared commit ancestry when merging, or rebase the remaining branches after squash/rebase merges so already-merged layers disappear from their diffs.

Validation

• cargo fmt --all --check
• cargo clippy --workspace --all-targets --release --locked -- -D warnings
• cargo test --workspace --locked: 269 passed, 5 driver/manual tests ignored, zero failures (Windows x64).
• Unit tests cover reversal/rearm, exclusive stages, delayed Hip Fire, clean release and native-mode preservation. The SDL virtual-controller -> engine -> ViGEm -> real XInput loopback verifies Hair Trigger, two-stage mapping and delayed Hip Fire.

All new tools are disabled by default. No additional dependencies are added. Cross-platform CI results are reported by GitHub checks.
