Module parsing 

Parsing stage: compiled descriptor → CodeGenMetadata.

This is the first stage of the code-generation pipeline. It walks every message, enum, and service in a FileDescriptorSet and extracts the annotations that drive generation into a structured, runtime-friendly form.

The generator reads the standard Google API extensions (google.api.http, google.api.resource, google.api.field_behavior, google.api.resource_reference), gnostic.openapi.v3.operation, and four trestle field options from proto/olai/trestle/v1/annotations.proto (olai.trestle.v1.response_header, emit_unpopulated, raw_body, request_header). Their field numbers are the *_EXTENSION module constants below. The core debug_redact option (google.protobuf.FieldOptions field 16) is handled in the message submodule. parse_file_descriptor_set is the entry point.
