feat(cfe,form): add borrowed form support across 6 skills

- cfe-borrow: borrow forms via Type.Name.Form.FormName, auto-borrow parent,
  generate Form.xml with BaseForm + metadata + empty Module.bsl
- form-edit: formEvents, elementEvents, callType on events/commands,
  auto-detect extension mode (IDs 1000000+)
- form-info: [EXTENSION] marker, callType on events/commands, BaseForm footer
- form-validate: callType value checks, extension ID range warnings,
  BaseForm presence, callType-without-BaseForm detection
- cfe-diff: form-level analysis in Mode A — borrowed/own forms,
  callType interceptors on events and commands
- cfe-patch-method: warn if Form.xml missing for .Form. paths
