feat: restructure as pnpm monorepo with Tauri desktop shell

- Migrate to packages/web + packages/desktop workspace layout via git mv
- Add Tauri v2 desktop shell with @tauri-apps/plugin-http for CORS bypass
- Configure Turborepo with package-level dependsOn build graph
- Add semantic-release with exec plugin for GHA output and disabled PR comments
- Fix http:default capability scope to allow all HTTP/HTTPS origins
- Add Vite Tauri integration (clearScreen, TAURI_DEV_HOST, target, envPrefix)
- Add semantic-release.yml and release.yml GitHub Actions workflows
- Fix all Biome lint errors (noArrayIndexKey, noNonNullAssertion, button types)
