Per mara on #14: 'make agent page not assume root path, links / api
calls need to be relative'. atlas's nginx side (#15) will mount the
per-agent UI at a prefix like /agent/<name>/ instead of its own
port; for the page to keep working under that prefix, every
in-page reference needs to resolve document-relative rather than
root-anchored.
Converted in this pass:
- HTML <link>/<script>/<img>/<a> hrefs in index.html, stats.html,
screen.html: '/icon' → 'icon', '/static/agent.css' →
'static/agent.css', back links '/' → './'.
- app.js fetch() targets ('/api/state' → 'api/state', /api/cancel,
/api/loose-ends, etc.), form actions ('/login/start', '/send'),
EventSource urls ('/events/stream', '/events/history').
- stats.js fetch() targets.
- screen.html WebSocket URL: was hardcoded as
ws(s)://host/screen/ws; now derived from document.baseURI via
new URL('screen/ws', document.baseURI) so the gateway prefix
flows through.
Slash-command labels (/cancel, /compact, …) and the dashboard-port
link (different port, intentionally absolute) intentionally
untouched.
Added a new 'Per-agent relative paths' section to docs/web-ui.md
covering the rationale + the trailing-slash gotcha (sub-pages like
/stats must NOT have a trailing slash, or 'static/app.js' resolves
under /stats/ instead of replacing the segment).
Functional code unchanged; build clean. Damocles + atlas can
proceed with the backend / nginx side without depending on this
landing first, but once both ship the agent page works under the
gateway-prefixed URL without further changes.
