Inject Designer redesign

Inject Designer redesign

Reworks scenario authoring into two linked, tool-agnostic surfaces (MISP, Suricata,
webhook, Python) that emit byte-compatible CEXF:

• Scenario Map — a drag-driven board of the whole exercise. Set prerequisites by
  dragging cards/handles onto other injects; drop onto the start rail or timed lane to
  change when an inject fires. Replaces the old read-only dependency table.
• Guided inject designer — a focused Task → Flow → Completion stepper, replacing the
  single flat form. Surfaces flow fields that were previously JSON-only
  (completion_trigger, followed_by).
• Completion + live test — a visual condition builder plus a FROM / WHERE / CHECK
  query builder for data_filtering (no hand-written jq), with a raw escape hatch. The
  right pane re-runs the rule against sample data as you type: verdict, score, and a
  per-condition breakdown.

Docs added under docs/: an evaluation-strategies guide and a comparison-operators
reference. README updated with fresh screenshots of all three surfaces.

Also in this release

• Python against live MISP data — the Python evaluation strategy can now run against
  data queried from MISP, not just the inject payload.
• Hall-of-fame toggle — new option to hide the hall of fame.
• Smarter inject tester — infers URL and method from query_context when testing a
  query_search.
• Bumped the bundled skillaegis-dashboard.

Fixes

• Docker — the container builds and runs again (the image was broken on main).
• README install notes now mention the required submodule.

Two things to adjust before posting:

• Replace in the changelog link with the repo owner (I can't read it — gh isn't authenticated here; the compare URL works once filled in).
• If you'd rather keep the note strictly redesign-focused, drop the "Also in this release" / "Fixes" sections — but I'd keep them, since the Docker fix is genuinely notable for anyone who tried the previous main.
