Summary

• Tighten README, architecture, and DocC wording around VLCKit comparison, discovery/renderers, PiP, CI, release, and build claims.
• Remove stale or transitional source comments while preserving behavior.
• Validate relative Markdown links and DocC generation after the cleanup.

Validation

• git diff --check
• swiftformat Sources/SwiftVLC Package.swift --lint --strict
• ./scripts/doc-coverage.sh --json
• swift package --disable-sandbox generate-documentation --target SwiftVLC
• relative Markdown link check across README, ARCHITECTURE, and DocC files

Pull request overview

Documentation-focused cleanup that tightens wording across README/ARCHITECTURE/DocC and refines inline source comments to better describe SwiftVLC’s behavior (discovery/renderers, PiP, typed errors, concurrency, logging, etc.) without changing runtime logic.

Changes:

• Reword DocC articles and README sections for clearer, more precise descriptions (metadata, discovery/casting, concurrency model, PiP, CI/testing claims, VLCKit comparison).
• Polish/trim inline comments across core types (Player, EventBridge, Logging/LogNoiseFilter, playlists, PiP, thumbnails).
• Update architecture documentation to reflect current internal components (e.g., Broadcaster-based fan-out, LogBroadcaster naming).
