feat(llm-security): v7.7.0 — HTML-rapport for alle 18 skill-kommandoer

Hver /security <cmd> som produserer rapport printer nå en klikkbar
file://-lenke til en self-contained HTML-versjon. Levert over fem
sesjoner; sesjon 5 wirer de 14 resterende skill-filene + slipper
v7.7.0 (versjonsbump + docs).

Sesjon-historikk:
- Sesjon 1 (0dc7ff4) — playground katalog list-view + builder-pane med
  copy-knapp på alle 18 rapporter
- Sesjon 2 (86d6ecd) — playground prosjekt-surface opprydding
  (stub-screen + topbar-splitt)
- Sesjon 3 (fa5fb48) — extract 18 inline parsers + 18 inline renderers
  fra playground til canonical ESM-modul scripts/lib/report-renderers.mjs
  (playground beholder bit-identisk inline-kopi siden ESM import ikke
  fungerer fra file://)
- Sesjon 4 (db80854) — ny zero-dep CLI scripts/render-report.mjs
  (stdin/file/stdout-modus, kebab→camel commandId-routing, ~140 KB
  self-contained HTML med 6 inlined DS-stylesheets + lokal .report-table,
  absolutte file://-paths for Ghostty cmd-click). 4 skills wired:
  scan, audit, posture, deep-scan.
- Sesjon 5 (denne) — 14 resterende skills wired: plugin-audit, mcp-audit,
  mcp-inspect, ide-scan, supply-check, dashboard, pre-deploy, diff,
  watch, registry, clean, harden, threat-model, red-team. Hver skill-fil
  har nå en HTML Report-step som instruerer Claude å skrive markdown
  verbatim, kjøre CLI, og appende klikkbar file://-lenke til respons.

Release-arbeid:
- Versjonsbump v7.6.1 → v7.7.0 i 6 plugin-filer + 2 rot-filer
  (package.json, .claude-plugin/plugin.json, README badge, CLAUDE.md
  header + state-seksjon, docs/version-history.md, plugin Recent versions-
  tabell, rot README plugin-entry, rot CLAUDE.md plugin-katalog)
- CHANGELOG [7.7.0] med full historikk fra sesjon 1-5
- docs/version-history.md v7.7.0-seksjon

Verifisert:
- 18/18 commandIds i CLI gir > 138 KB self-contained HTML
- 1819/1820 tester grønne (pre-compact-scan-perf-flake fyrte under last,
  passerer i isolasjon på 1582 ms — pre-eksisterende, defer til v7.7.x)
- 18/18 skill-filer har HTML Report-step
- Ingen kildefil-treff på 7.6.1 utenfor historiske changelog/version-
  history/README releases-tabell

Ingen scanner- eller hook-atferdsendringer — purely additive surface.

+## Step 5: HTML Report
+
+After producing the markdown diff report above:
+
+1. Compute a temp markdown path:
+   ```bash
+   node -p "require('path').join(require('os').tmpdir(), 'sec-diff-' + Date.now() + '.md')"
+   ```
+2. Use the Write tool to save the **entire markdown report you just produced** (banner with baseline+current timestamps + Summary table + New + Resolved + Moved sections + Advisory) to that temp path. Verbatim.
+3. Run the renderer:
+   ```bash
+   node <plugin-root>/scripts/render-report.mjs diff --in "<temp-md-path>"
+   ```
+   The CLI writes `reports/diff-<YYYYMMDD-HHmmss>.html` relative to CWD and prints `file:///abs/path.html` on stdout.
+4. Append to your response (markdown link, no bare URL):
+
+   > **HTML-rapport:** [Åpne i nettleser](file:///abs/path.html)
+
+If the CLI exits non-zero, mention the error but do not block — the markdown report above is the primary deliverable.
