Description:
Release 0.4.3 — Fixes type annotations, IDE resolution issues, and improves developer experience for clip(), Shot, and CaptionAsset APIs.

Changes:

• Fix VideoAsset/AudioAsset start/end type from int to Optional[float] (asset.py)
• Fix clip() return type from str to SearchResult — resolves unresolved .play() and .get_shots() in IDEs (video.py)
• Add Literal type validation for clip() content_type and model_name params (video.py)
• Pass stream_url/player_url from search API response to Shot objects (shot.py, search.py)
• Add warnings.warn() for CaptionAsset(src='auto') when video indexing is required (editor.py)
• Bump videodb-capture-bin dependency to >=0.2.10 (setup.py)
• Bump version to 0.4.3 (about.py)

Related Issues:

• Addresses ENG-161 — start parameter type mismatch (int vs float warning)
• Addresses ENG-162 — model_name / content_type validation on clip()
• Addresses ENG-163 — Unresolved play() and get_shots() on clip result
• Addresses ENG-165 — stream_url and player_url are None in Shot object
• Addresses ENG-166 — Stream not played after adding subtitles (CaptionAsset indexing warning)
• Addresses ENG-167 — Editor 500 clips internal server error (server-side, not SDK)

Testing:

• Verified VideoAsset(asset_id, start=1.5, end=3.0) no longer raises type warnings
• Verified video.clip() returns SearchResult — IDE resolves .play() and .get_shots()
• Verified clip() shows autocompletion for content_type ("spoken", "visual", "multimodal") and model_name ("basic", "pro", "ultra")
• Verified Shot.stream_url is None from search (server doesn't send per-doc URLs), populated after compile() or shot.generate_stream()
• Verified CaptionAsset(src='auto') emits a UserWarning about indexing requirement
• ENG-167 (500 clips / internal server error) is a server-side limit — no SDK fix needed

Looks good to me
