feat: add sitrep-panel skill

Live local HTML progress report (status board, running narrative,
screenshots, newest-first log) served on localhost via a stdlib-only
Python server, so a human can watch a long/delegated agent task
without reading the raw transcript. Adapted from dbl8005/sitrep-panel
(MIT), evaluated and drafted via Codex per this fleet's standard
skill-candidate review process. Bundled server and HTML template
copied unmodified from upstream.
