Interface MetadataHandler

crates/openshell-sandbox/src/metadata_server.rs:32–40

Handler for cloud metadata HTTP requests. Implementors receive the parsed HTTP method, path, raw request bytes, and a bidirectional stream to write the response. The handler owns the response format (status, headers, body) — the server only does TCP accept and HTTP request-line parsing.
