Description:
Release 0.2.3 — Sync Node SDK fixes with Python SDK 0.4.3. Fixes type safety for clip(), wires up Shot stream URLs from search results, adds CaptionAsset indexing warning, adds languageCode to generateTranscript, and updates capture binary + channel config.

Changes:

• Remove transcript from channel config, add isPrimary — sync with Python SDK
• Update capture binary to v0.2.10 with new checksums
• Add literal union types for clip() contentType ('spoken' | 'visual' | 'multimodal') and modelName ('basic' | 'pro' | 'ultra')
• Fix SearchResponse type: stream_url → stream_link to match server field name
• Pass streamUrl/playerUrl from search API response to Shot objects in SearchResult
• Add console.warn for CaptionAsset when src='auto' about indexing requirement
• Add languageCode param to generateTranscript()

Related Issues:

• Addresses ENG-161 — Asset type mismatch (Node uses number, already correct)
• Addresses ENG-162 — modelName / contentType validation on clip()
• Addresses ENG-163 — clip() return type (Node already returned SearchResult)
• Addresses ENG-165 — streamUrl and playerUrl are undefined in Shot object
• Addresses ENG-166 — Stream not played after adding subtitles (CaptionAsset indexing warning)

Testing:

• Build passes clean (npm run build)
• clip() now shows IDE autocompletion for contentType and modelName literal values
• Shot.streamUrl is undefined from search (server doesn't send per-doc URLs), populated after compile() or shot.generateStream()
• CaptionAsset() with default src='auto' emits console warning about indexing
• generateTranscript(false, 'en') passes language_code to server
• Channel config: isPrimary replaces transcript in RecordingChannelConfig
