fix: correct hardcoded folder paths to use underscores

- Fix transcript-extract.sh: `00 Inbox/Clippings` → `00_Inbox/Clippings/`
- Fix firecrawl-batch.sh: `00 Inbox/Clippings` → `00_Inbox/Clippings/`
- Add `-o|--output-dir` flag to firecrawl-batch.sh for custom paths
- Fix update-attachment-links.js: `05 Attachments` → `05_Attachments`
- Fix fix-renamed-links.js: `05 Attachments` → `05_Attachments`
- Fix GEMINI_VISION_QUICK_START.md example paths
- Update README.md with new flag documentation

All folder paths now match actual repo structure (underscores not spaces).
This prevents scripts from failing due to incorrect directory references.

Fixes #9
