v0.1.3 — English README as primary, Spanish preserved as README.es.md

Addresses feedback from multiple reviewers on the launch thread asking
for non-Spanish primary documentation. Also adds a framing quote from
community feedback (u/dashingsauce on Reddit) that captures the project
positioning better than prior phrasing.

- README.md now in English with language switcher to Spanish version
- README.es.md preserves the original Spanish content with switcher to English
- Added missing references in structure section (i18n.tsx, watcher.test.ts, events-db.ts)
- Added Discussions link to community section
