M1: Parse comment-based help from scripts/modules into canonical model

[jeffpatton1971]

Implement a parser that reads comment-based help from functions/scripts in a module path and maps it into the canonical Core help model.

Scope constraints (M1)

• Support scripts/modules from a filesystem path (examples folder).

• Parse only what you need for “minimal valid MAML”:

  • Synopsis
  • Description
  • Parameters (name + description)
  • Examples (code + remarks) if present

• If fields are missing, produce safe defaults (empty strings / empty lists), but do NOT scaffold placeholders yet (that’s later).

Definition of done

• Parser returns ModuleHelp with at least 1 CommandHelp.

• At least one CommandHelp includes:

  • Name
  • Synopsis (fallback allowed)
  • Parameter list (can be empty)

Acceptance checks

• Unit test against examples/with-comment-help ensures at least 1 command discovered and mapped.
