agent: cutover — index.html now serves the Preact rewrite, app.js deleted

mara: 'i merged this without realizing you still did not delete the
old code. pls follow up with ripping out the old code.'

- index.html: dropped the old static header/main/composer/overflow-
  menu markup and app.js's <script> tag. Now just <div id=preact-root>
  + <script src=static/main.js>. main.css's <link> lands after
  agent.css's — cascade order argus flagged matters for LoginFlow's
  .login-card / MetaNav's popover to win against agent.css's legacy
  rules, confirmed explicitly rather than assumed at this exact step.
- build.mjs: app.js dropped from the esbuild entryPoints (stats.js
  keeps its own bundle, unaffected — separate page, separate script).
- frontend/packages/agent/src/app.js deleted (1717 lines). screen.html
  has its own inline <script>, untouched — never depended on app.js.
- docs/web-ui/agent.md: rewrote the Header section to describe the
  real Preact component tree and the badges+pills-together layout
  (deferred from the earlier commits on this PR specifically so it
  wouldn't describe a hybrid state — this is that promised follow-up).
  Touched up the one other app.js-specific mention in the endpoints
  section. Left the Main/composer/side-panel/live-view/slash-command
  sections alone — behavior there is unchanged, verified faithfully
  ported throughout this PR's earlier commits.

Verified against the REAL dist/index.html (not the dev-preview
harness) — a scratch mock server serving the actual built output
end-to-end, screenshotted clean. tsc --noEmit clean, build clean, both
pre-push lints clean.
