Serves a localhost page in the pseudo-skill register with the
reference markers as clickable buttons: clicks land in
<workdir>/events.jsonl, a persistent Monitor tail wakes the session,
the session rewrites page.html, and the browser live-reloads over SSE.
Actions per marker: expand / show real code / explain / ask, plus a
page-level ask box; anchors become forge deep-links when the project
has a reachable remote; incidental findings are surfaced on the page
as anchored notes.
The port is configured in one place (the PORT constant atop
scripts/server.py; --port overrides per run). Mechanics proven live
against the aura repo before extraction into this skill.
