chore: update all dependencies to latest versions

- Updated all devDependencies and dependencies to their latest versions
- Added @internationalized/date to fix bits-ui peer dependency (3.7.0 → 3.11.0)
- Upgraded eslint-plugin-tailwindcss to 4.0.0-beta.0 to support tailwindcss v4
- Removed deprecated @types/uuid (uuid v13 provides its own type definitions)
- Notable upgrades: svelte 5.38→5.53, vite 7.1→7.3, vitest 3.2→4.0,
  monaco-editor 0.52→0.55, mermaid 11.12.0→11.12.3, eslint 9.39→10.0,
  @sveltejs/kit 2.37→2.53, typescript 5.9.2→5.9.3, husky 8→9
