init implementation for browser metadata parsing

[bretth18]

Description

This PR introduces a new TrackMetadataCleaner utility to clean up track metadata from web sources, integrates it into the scrobbling flow, and updates the Xcode project configuration to include the new files and tests. It also extends the NowPlayingFetcher to provide the bundle identifier of the current application, enabling smarter metadata handling for tracks coming from browsers and other web sources.

Track metadata cleaning improvements:

• Added the new TrackMetadataCleaner.swift utility to the project, along with TrackMetadataCleanerTests.swift for unit testing. These files are now included in the project and test targets (scrobble.xcodeproj/project.pbxproj). [1] [2] [3] [4] [5]
• Integrated TrackMetadataCleaner.cleanIfWebSource into the Scrobbler logic to sanitize track metadata from web sources before further processing, improving the quality of scrobbled data (Scrobbler.swift). [1] [2]

NowPlayingFetcher enhancements:

• Updated NowPlayingFetcher to track and expose the bundleIdentifier of the current application, and to include it in the fetchCurrentTrackInfo() method. This enables downstream logic to distinguish between native apps and browsers (NowPlayingFetcher.swift). [1] [2] [3] [4]
• Updated all call sites and signatures in Scrobbler to handle the new bundleIdentifier field when fetching track info (Scrobbler.swift). [1] [2]

Project file and configuration updates:

• Registered the new source and test files in the Xcode project, ensured correct group placement, and incremented the project version. [1] [2] [3] [4] [5]
• Fixed an ordering issue with FriendsFilterView.swift in the project file. [1] [2] [3]

These changes improve the accuracy of scrobbled metadata, specifically for tracks played in browsers, and lay the groundwork for more robust handling of various media sources. This unit of work covers the exact case described in #12 , but does not cover cases where a non-DSP channel has uploaded the audio (e.g this track will still return "VNRD - Distant Strangers - Do Anything [DS 001]")

Future work

• Add optional track metadata resolver to clean metadata pre-scrobble

How to test

• Ensure all checks pass
