test: regression runner diffs dist/claude-code against pre-refactor snapshot

- Add tests/regression/run.sh that builds dist/claude-code and compares
  against snapshot, excluding runtime-only artifacts (.mbifc-manifest,
  .mcp.json, .claude-plugin/plugin.json)
- Fix adapters/lib.sh agent_body: preserve '---' section dividers in body
  (awk now only skips '---' while still inside frontmatter, fm < 2)
- Fix adapters/claude-code/adapter.sh: change 'read' capability to expand
  to only 'Read', appending 'Glob, Grep' at end of tools list to match
  snapshot ordering
- Update snapshot to reflect intentional refactor changes: hook JSON schema
  (.args.* instead of .tool_input.*), wrapper scripts, settings.json with
  wrapper paths, and consistent tool ordering for postman/sorter
