ci: dogfood interactive AppMap before/after PR comparisons

[tryingET]

Purpose

Use appmap-node as the end-to-end dogfood project for the frozen AppMap before/after comparison contract.

The workflow builds exact base/head revisions, records deterministic AppMaps, generates portable appmap.comparison schema-v1 bundles, opens the real generated artifact in the pinned VS Code extension host, and verifies the review publisher and skill contract.

Final acceptance run
