Some controllers' rear buttons replay several ordinary inputs. This adds a Combinations tab so a chord such as Capture + B can trigger one keyboard or mouse shortcut. A matched combination consumes its inputs. Outputs can use a fixed pulse or stay held until a button is released.

• Add named actions, combination recording, and multi-key shortcut capture on Windows.
• Save controller profiles and reusable actions to a configuration file. A different controller model can import the actions and assign its own inputs.
• Restore full Switch Pro input reports on Bluetooth when leaving Keep native, so Capture becomes available again.
• The new panels use English fallback text in the Simplified Chinese locale.

Validation: cargo fmt --all --check and cargo test --locked --workspace --release on Windows x64 against current main (290 passed, 5 ignored, 0 failed).

On the previous local build, an Ultimate 2C Bluetooth trace of R4 programmed as Capture + B showed matching SDL timestamps and update boundaries for both buttons across ten press/release cycles. That trace was sent separately. Timing for R4 programmed as Capture + A remains unmeasured.
