refactor: update markdown parser

- Removed the `nodes` field from the `Memo` interface in `memo_service.ts`.
- Updated the `createBaseMemo` function and the `Memo` message functions to reflect the removal of `nodes`.
- Cleaned up the serialization and deserialization logic accordingly.

chore: remove code-inspector-plugin from Vite configuration

- Deleted the `codeInspectorPlugin` from the Vite configuration in `vite.config.mts`.
- Simplified the plugins array to include only `react` and `tailwindcss`.
