docs: update CLAUDE.md to reflect recent AI refactoring, UI redesign, and state changes

Browse Source 
- state.rs: remove stale schema_cache/columns_cache refs; add
  overview_cache, tables_by_db_cache, ai_settings, MCP channels,
  ClickHouse flavor
- commands/: list all current modules (ai, chat, chat_tools, memory,
  settings) instead of an outdated subset
- frontend: document tool-calling chat architecture (tool-registry.ts,
  ChatPanel) replacing the former AiBar/explain/fix/ChartPreview
- ui: mention "Graphite & Honey" theme, IBM Plex Mono, custom
  CodeMirror theme
- conventions: add rule for adding AI chat tools

### Backend (src-tauri/src/)
- **`state.rs`** — `AppState`: holds `RwLock<HashMap<connection_id, PgPool>>`, read-only flags, config path. Connections default to read-only.
- **`state.rs`** — `AppState`: holds connection pools (`pools`, `ch_clients`), read-only flags, DB flavors (PostgreSQL/Greenplum/ClickHouse), config path, chat-agent caches (`overview_cache`, `tables_by_db_cache`), MCP signal channels, and `ai_settings`. Connections default to read-only.
- **`error.rs`** — `TuskError` enum with `thiserror`, serialized as string for IPC. `TuskResult<T>` type alias.
- **`utils.rs`** — `escape_ident()` for safe SQL identifier quoting.
- **`commands/`** — one module per domain (connections, queries, schema, data, export, management, history, saved_queries). Each function takes `State<'_, AppState>` and returns `TuskResult<T>`.
- **`commands/`** — one module per domain (connections, queries, schema, data, export, management, history, saved_queries, ai, chat, chat_tools, memory, settings). Each function takes `State<'_, AppState>` and returns `TuskResult<T>`.
- **`models/`** — serde-serializable structs matching TypeScript types.
SQL safety: identifiers use `escape_ident()`, data queries use sqlx parameterized queries. Read-only mode wraps queries in `SET TRANSACTION READ ONLY` + `ROLLBACK`.

- **State**: Zustand store (`stores/app-store.ts`) — connections, active connection/database, tabs, read-only flags, pg version.
- **Data fetching**: TanStack React Query hooks in `hooks/` — one hook per domain, wrapping `src/lib/tauri.ts` functions.
- **UI**: shadcn/ui + Radix primitives, Tailwind CSS 4, dark mode via next-themes. SQL editor uses CodeMirror.
- **AI chat**: tool-calling architecture — backend commands in `commands/chat.rs` / `commands/chat_tools.rs`, frontend tool definitions in `components/chat/tool-registry.ts`. Chat panel (`ChatPanel.tsx`) replaces the former inline `AiBar`, explain/fix, and chart-preview UIs.
- **UI**: shadcn/ui + Radix primitives, Tailwind CSS 4, warm dark "Graphite & Honey" theme (IBM Plex Mono, honey accent). CodeMirror SQL editor with a custom theme from `src/lib/editor-theme.ts`.
- **Layout**: resizable panels (sidebar + main area with tab bar).

- **Path alias**: `@` maps to `./src`
- **Rust errors**: always use `TuskError` variants, never `unwrap()` in commands
- **New PG types**: add conversion case in `pg_value_to_json()` in `commands/queries.rs`
- **AI chat tools**: add Rust-side tool implementation in `commands/chat_tools.rs` and register it in both the backend dispatch (`ChatTool`) and the frontend `components/chat/tool-registry.ts` (schema, display component, card builder).
