sync: Idea Genealogy + Quick Capture Overhaul

From private repo:

Idea Genealogy:
- Required edge explanations across UI/tools/API/MCP
- Inferred edge schema (category/type/confidence)
- Added part_of relationship type
- Connection UI chips (Made by / Part of / Came from / Related)

Quick Capture Overhaul:
- Jina.ai fallback for JS-rendered sites (Twitter, SPAs)
- Simplified UI: removed mode buttons, auto-detect input type
- Renamed to "Add Stuff", moved to top-right
- Auto-edge creation from description entities
- Increased content summary length (500→1500 chars)

Description Generation Fix:
- Simplified prompt to "what is this"
- Added link/dimensions context
- Better creator attribution

+- enhancedDescription should be thorough - cover key points, arguments, and takeaways
+- Aim for 3-6 paragraphs or 800-1500 characters - don't artificially truncate
 - Include 3-8 relevant semantic tags (not just generic ones)
-- Make description informative and contextual
 - For academic papers, include tags like: research, academic, paper, plus domain-specific tags
 - For AI/ML papers, include: ai, machine-learning, artificial-intelligence, deep-learning
 - For economics papers, include: economics, finance, markets, policy
