chore: remove unrelated tracked files and update .gitignore

- Remove .vite/ cache directory from tracking
- Remove .vscode/settings.json (IDE-specific)
- Remove stale dashboard/dist build assets (old hashes)
- Remove root PDF duplicate of edict_agent_architecture.md
- Add .vite/ and .vscode/ to .gitignore
