Add audio device listing and selection APIs

[JamieW105]

Scripts can now list and choose audio devices through Audio.get_output_devices(), get_input_devices(), set_output_device(id), and set_input_device(id) in all language bindings. Lists return opaque IDs and names; passing null chooses the system default.

Windows output switching opens the replacement stream before dropping the current stream, preserving playback on failure. Input selection validates and retains a device; microphone capture is not implemented. Headless platforms return empty lists and report unavailable selection. IDs are scene-local snapshots and must be refreshed after another enumeration of the same direction.

Companion website documentation: Rustic-Game-Engine/docs#20

Validation:

• 96 engine-play and engine-scripting tests passed; targeted device tests rerun after the final C parser adjustment.
• Formatting and Clippy for both changed crates passed with warnings denied.
• Windows native audio module cross-target check and Clippy passed against rodio 0.21.1/cpal 0.16.0.
• C17 transport test (including escaped Unicode and result lifetime), C++20 compilation, JavaScript syntax and Python compilation passed.
• Website build, lint, TypeScript, security audit, documentation tests and API example checks passed.
• Windows installer build is pending in this PR's CI; local execution requires Windows.

Build the required Windows installer

This new Windows-only audio path has not completed the repository-required packaging validation: the commit’s validation notes explicitly leave the installer build pending in CI. Before treating the feature as complete, run tools/build-windows-installer.ps1 and confirm that it produces a fresh dist\RusticGameEngine-Setup-*.exe; otherwise failures in the Windows integration or installer packaging remain unverified.
