Replaces kimi-k2p5 for all vision tasks. K2.5 was outputting chain-of-thought
reasoning instead of JSON for non-English docs, requiring a fallback path.
qwen3-vl works first try, no retry needed, preserves original language correctly.
- Add 'DO NOT translate, preserve original language' to vision prompts
- Shorter/tighter JSON prompt to reduce K2.5 reasoning verbosity
- Fallback: when AnalyzeWithVision returns no JSON, do AnalyzePageOnly (plain text) then AnalyzeText (classify)
- Fallback to AnalyzePageOnly for single-page PDFs with empty/placeholder full_text
- Switch model back to kimi-k2p5 (only vision model on this Fireworks account)
- Build with CGO_ENABLED=1 -tags fts5 (required for SQLite FTS5)
