feat: expand template window from 6 months to 1 year and add robust fetcher

- Changed template time window from 6 months to 1 year
- Added robust incremental template fetcher that saves as it goes
- Successfully fetched and saved 399 templates (up from 199)
- Added npm script 'fetch:templates:robust' for better error handling
- Templates now save incrementally to prevent data loss on errors
