update: ddd folder structure for backend and frontend

[maximedogawa]

Summary by CodeRabbit

• New Features

  • Background app startup now resumes persisted bot connections, runs a local HTTP server, and exposes connect/disconnect/status commands.
  • Added Ollama probing and chat integration for model selection and chat replies.

• Refactor

  • Reorganized backend into modular infrastructure and modules (bot, ollama, shared state, repository).
  • Command handling and persistence moved to dedicated modules.

• Chores

  • Added lint/typecheck and Rust check scripts; simplified pre-commit hooks to use project scripts.

• Documentation

  • Added architecture and design reference doc.

• Tests

  • Updated E2E imports to use new shared API config.

📝 Walkthrough

Walkthrough

Refactors Tauri backend: moves app bootstrap into app.rs, extracts bot lifecycle, HTTP server, repository, Ollama service, and shared state; updates frontend to use new modules/* and shared/* barrels; adds persistence repository and npm/rust scripts; adjusts e2e test imports and documentation.

Changes

Cohort / File(s)	Summary
Tauri Entrypoint src-tauri/src/lib.rs, src-tauri/src/app.rs	Moved Tauri bootstrap into app.rs; lib.rs now delegates to app::run(). New app::run() manages logging, AppState, background tasks (resume bot, start HTTP server), and Tauri commands.
Infrastructure: bot lifecycle & HTTP server src-tauri/src/infrastructure/mod.rs, src-tauri/src/infrastructure/bot_lifecycle.rs, src-tauri/src/infrastructure/http_server.rs	Added bot_lifecycle/http_server modules; handlers updated to use new modules::bot and shared::state paths, call repository persistence, and spawn/stop bots via bot_service.
Modules: bot (backend) src-tauri/src/modules/bot/mod.rs, src-tauri/src/modules/bot/commands.rs, src-tauri/src/modules/bot/repository.rs, src-tauri/src/modules/bot/service.rs	New bot module with commands (Tauri commands), repository (persist/load/clear ConnectionData), and service (bot runtime logic delegating to ollama service).
Modules: ollama (backend) src-tauri/src/modules/ollama/mod.rs, src-tauri/src/modules/ollama/constants.rs, src-tauri/src/modules/ollama/service.rs	New Ollama module with endpoint constants and HTTP-backed active_model() and chat() functions.
Shared state (backend) src-tauri/src/shared/mod.rs, src-tauri/src/shared/state.rs	Introduced shared::state; moved LogEntry and AppState changes; removed file-based persist/load/clear methods from AppState (moved to repository).
Frontend module reorg src/modules/bot/index.ts, src/modules/bot/types.ts, src/modules/bot/api/index.ts, src/modules/bot/store/appSessionStore.ts, src/modules/bot/components/..., src/modules/ollama/index.ts, src/modules/ollama/types.ts, src/modules/ollama/api/index.ts	Created modules/bot and modules/ollama barrels and types; moved fetchOllamaModel/OllamaProbe to modules/ollama; added PengineHealth type and bot API exports; updated store/component entry points.
Frontend import updates src/App.tsx, src/pages/DashboardPage.tsx, src/pages/LandingPage.tsx, src/pages/SetupPage.tsx, src/shared/ui/TopMenu.tsx	Updated numerous imports across pages and UI to the new modules/* and shared/* paths.
Components: Setup & Terminal src/modules/bot/components/SetupWizard.tsx, src/modules/bot/components/TerminalPreview.tsx	Redirected imports to new module paths; removed commented step labels in SetupWizard; switched TerminalPreview PENGINE import to api.
E2E tests e2e/setup-dashboard.spec.ts	Updated test imports to use src/shared/api/config for API base constants.
Tooling & docs .husky/pre-commit, package.json, doc/design/README.md	Pre-commit hook simplified to npm scripts; added lint:fix, typecheck, rust:fmt, rust:lint, rust:check scripts; added architecture/design doc.
Small refactors various (imports, small relocations) + many files	Multiple import path changes and small relocations across frontend/backend to match new module layout.

Poem

🐰
I hopped through modules, stitched and neat,
Bot, Ollama, state — each found its seat,
Files rearranged with tidy cheer,
A carrot for structure, and clean code to steer!
