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
