fix(web): fix stale state bugs, add real-time updates, and build verification pipeline

- Fix kanban board columns not adapting to available width (w-64 → flex-1)
- Fix workspace name not updating in sidebar after save in settings
- Fix comments leaking across issues when navigating between issue details
- Fix duplicate issue appearing on create (race between callback and WebSocket)
- Add real-time WebSocket listeners for agents and inbox pages
- Add `make check` one-click verification pipeline (typecheck + tests + E2E)
- Add E2E test fixtures for self-contained test data setup/teardown
- Add settings E2E test and updateWorkspace unit test
- Make `make start/setup` reuse existing PostgreSQL if already running
- Update CLAUDE.md with AI agent verification loop and E2E test patterns

 ## 7. Minimum Pre-Push Checks
 
 ```bash
-pnpm typecheck
-pnpm test
-make test
+make check    # Runs all checks: typecheck, unit tests, Go tests, E2E
+```
+
+For individual checks during development:
+```bash
+pnpm typecheck        # TypeScript type errors only
+pnpm test             # TS unit tests only (Vitest)
+make test             # Go tests only
+pnpm exec playwright test   # E2E only (requires backend + frontend running)
+```
+
+## 8. AI Agent Verification Loop
+
+After writing or modifying code, always run the full verification pipeline:
+
+```bash
+make check
+```
+
+This runs all checks in sequence:
+1. TypeScript typecheck (`pnpm typecheck`)
+2. TypeScript unit tests (`pnpm test`)
+3. Go tests (`go test ./...`)
+4. E2E tests (auto-starts backend + frontend if needed, runs Playwright)
+
+**Workflow:**
+- Write code to satisfy the requirement
+- Run `make check`
+- If any step fails, read the error output, fix the code, and re-run `make check`
+- Repeat until all checks pass
+- Only then consider the task complete
+
+**Quick iteration:** If you know only TypeScript or Go is affected, run individual checks first for faster feedback, then finish with a full `make check` before marking work complete.
+
+## 9. E2E Test Patterns
+
+E2E tests should be self-contained. Use the `TestApiClient` fixture for data setup/teardown:
+
+```typescript
+import { loginAsDefault, createTestApi } from "./helpers";
+import type { TestApiClient } from "./fixtures";
+
+let api: TestApiClient;
+
+test.beforeEach(async ({ page }) => {
+  api = await createTestApi();       // logged-in API client
+  await loginAsDefault(page);        // browser session
+});
+
+test.afterEach(async () => {
+  await api.cleanup();               // delete any data created during the test
+});
+
+test("example", async ({ page }) => {
+  const issue = await api.createIssue("Test Issue");  // create via API
+  await page.goto(`/issues/${issue.id}`);             // test via UI
+  // api.cleanup() in afterEach removes the issue
+});
 ```
