build(web): replace Playwright MCP with project-scoped Playwright CLI

- feat: add `.agents/skills/playwright-cli/` with complete Skill markdown, agent interface, and 9 reference files covering session management, spec-driven testing, video recording, tracing, storage, request mocking, element attributes, test debugging, and running custom code - feat: add `.playwright/cli.config.json` to configure the Playwright CLI - feat: add `web/package.json` `playwright:cli` script that resolves `playwright cli` from the repo root - build: remove `@playwright/mcp` dependency from `web/package.json` - build: set `XDG_CACHE_HOME` in `mise.toml` - build: delete `.codex/config.toml` (MCP server config) - docs: update `README.md`, `docs/web/roadmap.md`, `docs/web/decisions.md`, and `web/README.md` to reflect the new Playwright CLI approach

+# Request Mocking
+
+Intercept, mock, modify, and block network requests.
+
+## CLI Route Commands
+
+```bash
+# Mock with custom status
+mise exec -- npm run playwright:cli -- route "**/*.jpg" --status=404
+
+# Mock with JSON body
+mise exec -- npm run playwright:cli -- route "**/api/users" --body='[{"id":1,"name":"Alice"}]' --content-type=application/json
+
+# Mock with custom headers
+mise exec -- npm run playwright:cli -- route "**/api/data" --body='{"ok":true}' --header="X-Custom: value"
+
+# Remove headers from requests
+mise exec -- npm run playwright:cli -- route "**/*" --remove-header=cookie,authorization
+
+# List active routes
+mise exec -- npm run playwright:cli -- route-list
+
+# Remove a route or all routes
+mise exec -- npm run playwright:cli -- unroute "**/*.jpg"
+mise exec -- npm run playwright:cli -- unroute
+```
+
+## URL Patterns
+
+```
+**/api/users           - Exact path match
+**/api/*/details       - Wildcard in path
+**/*.{png,jpg,jpeg}    - Match file extensions
+**/search?q=*          - Match query parameters
+```
+
+## Advanced Mocking with run-code
+
+For conditional responses, request body inspection, response modification, or delays:
+
+### Conditional Response Based on Request
+
+```bash
+mise exec -- npm run playwright:cli -- run-code "async page => {
+  await page.route('**/api/login', route => {
+    const body = route.request().postDataJSON();
+    if (body.username === 'admin') {
+      route.fulfill({ body: JSON.stringify({ token: 'mock-token' }) });
+    } else {
+      route.fulfill({ status: 401, body: JSON.stringify({ error: 'Invalid' }) });
+    }
+  });
+}"
+```
+
+### Modify Real Response
+
+```bash
+mise exec -- npm run playwright:cli -- run-code "async page => {
+  await page.route('**/api/user', async route => {
+    const response = await route.fetch();
+    const json = await response.json();
+    json.isPremium = true;
+    await route.fulfill({ response, json });
+  });
+}"
+```
+
+### Simulate Network Failures
+
+```bash
+mise exec -- npm run playwright:cli -- run-code "async page => {
+  await page.route('**/api/offline', route => route.abort('internetdisconnected'));
+}"
+# Options: connectionrefused, timedout, connectionreset, internetdisconnected
+```
+
+### Delayed Response
+
+```bash
+mise exec -- npm run playwright:cli -- run-code "async page => {
+  await page.route('**/api/slow', async route => {
+    await new Promise(r => setTimeout(r, 3000));
+    route.fulfill({ body: JSON.stringify({ data: 'loaded' }) });
+  });
+}"
+```
