v2.33.3 — project_summary + timeline get_transcript

Two read tools that surface existing project state.

• Added project_settings(action="project_summary") → live structural readout: current page, timeline count and current timeline, and a media-pool inventory (folder/clip counts, clips by type, optional clip sample). A cheap "what's in this project right now" snapshot that needs no prior analysis.
• Added timeline(action="get_transcript") → reads the current timeline's subtitle track(s) as transcript text {text, cue_count, has_subtitles, cues}, with optional per-cue timecodes. Complements the clip-level get_transcription.

Live-validated on DaVinci Resolve Studio 21.0.0.
