chore: prepare v1.0.0 for Netlify deployment

Update version to 1.0.0 across package.json and changelog. Configure netlify.toml with Convex deployment URL (agreeable-trout-200.convex.site). Verify TypeScript type-safety for src and convex directories. Confirm Netlify build passes with SPA 404 fallback configured. Update TASK.md with deployment steps and files.md with complete file structure.
