Add a per-controller Lab page with independent DualSense/Edge L2 and R2 resistance, vibration and trigger-break effects. Five-second trials restore the saved profile; Stop, loss of ownership, disconnect and normal exit clear owned effects. Persistent effects require an explicit opt-in. SDL handles USB/Bluetooth framing and checksums.

This first layer provides the shared per-profile schema (including reserved settings for later tools), snapshot status, IPC protocol 2, numeric editors and English, Portuguese and Simplified Chinese Lab text. Only the Trigger Lab tab is exposed at this layer. Match resident and UI binaries. Live Lab input no longer automatically opens the extra-button mapper.

Dependencies and focused review

Stacked PR 1/7; depends on #9 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 c9a624a).

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: 261 passed, 5 driver/manual tests ignored, zero failures (Windows x64).
• DualSense hardware: resistance, vibration and trigger-break modes, including automatic restoration after five seconds, confirmed by the tester. Unit tests cover effect encoding, restoration, profile migration and UI navigation.

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