Wire execution-view source and stack handlers in DapDebugger

Adds DAP source, stackTrace, and loadedSources handlers backed by a
synthesized JobExecutionView. The view is served via sourceReference,
with a synthetic .yml path so clients pick YAML syntax highlighting.
User-visible text (path, name, content) is run through the secret
masker.

Adds three lifecycle methods to IDapDebugger:
  - OnJobStepsInitializedAsync seeds the view and synthesizes Post
    placeholders predictively from action Pre/Post metadata, so VS
    Code's sourceReference cache hits a stable view.
  - OnPostStepRegistered claims a predicted placeholder when the real
    Post IActionRunner is registered, or appends a new entry.
  - OnStepCompleted marks predicted Post placeholders as skipped when
    their Main step is skipped.
