Splicerr v1.15.1 pack navigation and drag/drop fixes

[dre4moff]

What changed

This PR prepares Splicerr v1.15.1 from the current upstream v1.15.0 base.

• Prevents dropped audio/file URLs from navigating the Tauri webview into the browser media player view.
• Changes pack artwork left-click behavior to open the pack's samples inside Splicerr.
• Moves the external Splice pack link to a right-click context menu action: View on Splice.
• Adds direct in-app pack filtering via parent_asset_uuid, with a text-search fallback when a pack UUID is unavailable.
• Updates macOS DAW Bridge settings status to show both installed plugin locations: AU component and VST3.
• Bumps app/package version to 1.15.1 and adds release notes.

Why

Dragging samples out of the app could occasionally leave the window navigated to a fullscreen media player view. Also, clicking pack artwork previously opened Splice in the browser, while the expected workflow is to inspect the pack inside the app and keep the external link behind an explicit context-menu action.

Validation

• pnpm check
• cargo check --manifest-path src-tauri/Cargo.toml
• pnpm tauri build --bundles dmg

A fork release with the macOS DMG is available here: https://github.com/dre4moff/splicerr/releases/tag/v1.15.1

the initial v1.15 is buggy, the bridge sometimes doesn't update the bpm information to the main app instaneously, need to restart the playblack / retrigger the play button for the sample to play at the new bpm info value.

also there's bug the app closed but audio is still looping in the background so shutting down via task manager, this occurs while using the bridge and the app itself...

I run it using windows
