feat: propagate HCL inline comments on attributes to YAML output

[jccguimaraes]

Introduces an annotated wrapper type that threads trailing # comments from HCL attributes through the map[string]any pipeline. toYAMLNode unwraps it and attaches the comment as a LineComment on the YAML node, so any attribute-level comment in HCL appears inline in the generated YAML.

Validators that type-assert map values use unwrapAnnotatedMap to strip the wrapper before checking. The permissions-specific parsePermissionsBlock and permissionsMapNode helpers are removed — the general mechanism covers that case automatically.
