feat: validate model connectivity during uwf setup

Send a test completion request after configuration to verify the model
is reachable. If validation fails, warn the user and suggest trying a
different model or checking their settings.

+# Test Spec: uwf setup model connectivity validation (#335)
+
+## Context
+
+File: `packages/cli-workflow/src/commands/setup.ts`
+Test file: `packages/cli-workflow/src/__tests__/setup-validate.test.ts`
+
+After `cmdSetup` writes config, it should send a test chat completion request to verify the configured model is reachable. If validation fails, warn the user (don't abort — config is already saved).
+
+## Implementation Notes
+
+- Add a `validateModel(baseUrl, apiKey, model)` function that sends a minimal chat completion request (`POST /chat/completions` with `messages: [{role:"user",content:"hi"}]`, `max_tokens: 1`)
+- Returns `Result<void, string>` — ok if 2xx response, error with reason string otherwise
+- Use `AbortSignal.timeout(15_000)` for the request
+- Both `cmdSetup` and `cmdSetupInteractive` should call it after saving config
+- `cmdSetup` returns validation result in its return object: `{ ...existing, validation: { ok: true } | { ok: false, error: string } }`
+- `cmdSetupInteractive` prints a warning to console if validation fails, success message if it passes
+- Use the project logger (`createLogger`) — no raw `console.log` except in interactive CLI output (per CLAUDE.md)
+
+## Test Cases (vitest)
+
+### 1. `validateModel` — success path
+- Mock `fetch` to return `{ status: 200, ok: true, json: () => ({}) }`
+- Call `validateModel(baseUrl, apiKey, model)`
+- Assert returns `{ ok: true, value: undefined }`
+- Assert fetch was called with correct URL (`${baseUrl}/chat/completions`), correct headers (`Authorization: Bearer ${apiKey}`), correct body (model, messages, max_tokens: 1)
+
+### 2. `validateModel` — HTTP error (401 unauthorized)
+- Mock `fetch` to return `{ status: 401, ok: false, statusText: "Unauthorized" }`
+- Call `validateModel(baseUrl, apiKey, model)`
+- Assert returns `{ ok: false, error: <string containing "401"> }`
+
+### 3. `validateModel` — HTTP error (404 model not found)
+- Mock `fetch` to return `{ status: 404, ok: false, statusText: "Not Found" }`
+- Assert returns `{ ok: false, error: <string containing "404"> }`
+
+### 4. `validateModel` — network timeout
+- Mock `fetch` to throw `DOMException` with name `AbortError`
+- Assert returns `{ ok: false, error: <string containing "timeout" or "unreachable"> }`
+
+### 5. `validateModel` — network error (DNS failure, connection refused)
+- Mock `fetch` to throw `TypeError("fetch failed")`
+- Assert returns `{ ok: false, error: <string mentioning connectivity> }`
+
+### 6. `cmdSetup` — includes validation result on success
+- Mock global `fetch` for `/chat/completions` to succeed
+- Call `cmdSetup({ provider, baseUrl, apiKey, model, storageRoot })`
+- Assert returned object has `validation: { ok: true, value: undefined }`
+- Assert config files are still written (existing behavior preserved)
+
+### 7. `cmdSetup` — includes validation result on failure (config still saved)
+- Mock global `fetch` for `/chat/completions` to return 401
+- Call `cmdSetup({ ... })`
+- Assert returned object has `validation: { ok: false, error: ... }`
+- Assert `config.yaml` and `.env` are still written (validation failure doesn't prevent saving)
+
+### 8. `cmdSetupInteractive` — prints success message on validation pass
+- Mock `fetch` for both `/models` and `/chat/completions` to succeed
+- Mock stdin to provide valid selections
+- Capture console output
+- Assert output contains a success message like "Model verified" or "✓"
+
+### 9. `cmdSetupInteractive` — prints warning on validation failure
+- Mock `fetch`: `/models` succeeds, `/chat/completions` returns 401
+- Mock stdin for valid selections
+- Capture console output
+- Assert output contains a warning about model not being reachable and suggests trying a different model
+
+### 10. `validateModel` — request body correctness
+- Mock `fetch` to capture the request body
+- Call `validateModel(baseUrl, apiKey, "test-model")`
+- Assert body is `{ model: "test-model", messages: [{role: "user", content: "hi"}], max_tokens: 1 }`
+
+## Export Requirements
+
+- `validateModel` must be exported (for direct unit testing)
+- Signature: `async function validateModel(baseUrl: string, apiKey: string, model: string): Promise<Result<void, string>>`
+- `Result` type: `{ ok: true; value: T } | { ok: false; error: E }` (project convention)
+
+## Files to Create/Modify
+
+- **New**: `packages/cli-workflow/src/__tests__/setup-validate.test.ts` — all test cases above
+- **Modify**: `packages/cli-workflow/src/commands/setup.ts` — add `validateModel`, integrate into `cmdSetup` and `cmdSetupInteractive`

+## Key Concepts
+
+- **Workflow**: YAML definition with roles, conditions, and a routing graph; stored as a CAS node identified by its XXH64 hash.
+- **Thread**: A single workflow execution (ULID). State is an immutable CAS chain; active threads are indexed in \`threads.yaml\`.
+- **Step**: One moderator→agent→extract cycle. Run \`uwf thread step\` repeatedly until \`$END\`.
+- **CAS**: Content-Addressed Storage — all nodes are immutable and identified by hash.
+- **Role**: Named actor with goal, capabilities, procedure, output, and meta; the moderator routes between roles.
