docs: complete rewrite of CLAUDE.md and README.md to fix critical architecture misrepresentations

- Fix package name from non-existent split packages to single @trestleinc/replicate
- Correct all import paths: /client, /server, /ssr, /convex.config
- Document event-sourced component architecture (append-only event log)
- Prominently feature replicatedTable helper that auto-injects version/timestamp
- Fix API reference to match actual exports (remove non-existent helpers)
- Remove outdated documentation files (CHANGELOG.md, ROADMAP.md, example docs)
- Update all code examples with correct import paths and actual working code
