feat: Task decomposition for Tailwind/Radix/shadcn foundation setup

Decomposed "Foundation Setup - Install Dependencies & Configure Tailwind"
phase into 6 executable tasks:

1. Install Tailwind CSS, PostCSS & Autoprefixer
2. Map MUI theme to Tailwind design tokens
3. Setup CSS variables for dynamic theming
4. Install Radix UI primitives
5. Initialize shadcn/ui and setup component directory
6. Move MUI to devDependencies and verify setup

Tasks follow logical dependency chain with final human verification
checkpoint before proceeding with component migration.

+# CLI & Configuration
+
+`src/cli/` — CLI commands, `src/config/` — workspace configuration, `src/bin/` — entry point.
+
+## Entry Point
+
+`src/bin/cw.ts` — hashbang entry that imports and runs the CLI.
+
+## CLI Framework
+
+Uses **Commander.js** for command parsing.
+
+## Global Flags
+
+- `-s, --server` — Start coordination server in foreground
+- `-p, --port <number>` — Server port (default: 3847, env: `CW_PORT`)
+- `-d, --debug` — Enable debug mode (archive agent workdirs before cleanup)
+
+## Commands
+

+
+## Server Wiring
+
+The CLI is the composition root. It creates concrete implementations and passes them as `contextDeps`:
+
+```
+ServerContextDeps = Omit<TrpcAdapterOptions, 'eventBus' | 'serverStartedAt' | 'processCount'>
+```
+
+This includes all repositories, managers, and the credential manager. The server adds `eventBus`, `serverStartedAt`, and `processCount` at startup.
+
+## Workspace Configuration
+
+`src/config/` module:
+
+### .cwrc File
+JSON file at workspace root that marks a `cw` workspace:
+```json
+{ "version": 1 }
+```
+
+### findWorkspaceRoot()
+Walks up directory tree looking for `.cwrc` file. Returns the directory containing it, or throws if not found.
+
+### Schema
+Currently `{ version: 1 }` — extend with new top-level keys as needed.
+
+### Files
+| File | Purpose |
+|------|---------|
+| `types.ts` | CwrcConfig type definition |
+| `cwrc.ts` | findWorkspaceRoot(), readCwrc(), writeCwrc() |
+| `index.ts` | Public API exports |
