NEST UI runtime fix

Root cause

est/static/index.html line 201 had an extra backtick:
html += ...generated`; — a JavaScript syntax error that prevented the entire inline script from executing, leaving all three panels blank (conversation, world, memory) and no welcome message.

Fix

• Corrected to ...generated;.
• Audited the rest of the inline JS (balance checks +
  ode --check): no further defects found.

Guardrails added

est/tools/frontend_audit.py: extracts inline script, runs
ode --check (fallback balance check), optional --smoke.

est/tools/frontend_smoke.node.js: executes the real inline script in a DOM stub with backend-shaped snapshots; asserts welcome message, world canvas draw calls, memory stats/hypothesis, send/Enter flow, and control-button wiring.

• CI
  est job now runs rontend_audit.py --smoke.

Verification

• Node syntax check: OK. Balance checks: OK.
• DOM smoke: 8/8 assertions PASS (welcome, world renders, memory panel, hypothesis list, user/bot send, start wiring).
• Served page on 127.0.0.1:8765 contains the fixed line and zero double-backticks; browser tab loads clean (title METARGON NEST, no load error).
• Backend API confirmed: /api/state, /api/config respond; NEST unit suite 10/10 OK (incl. demo tests + server endpoints + frontend validation).
• Repo hygiene OK; CI YAML valid (jobs: repo-checks, python-v09, academy, generalization-audit, nest, rust).
