feat: serve OpenAPI spec at /api/v1/openapi.json

Registers a handler that serves the embedded OpenAPI 3.0 spec
(compiled into the binary via oapi-codegen) at a browseable
endpoint. Uses gen.GetSwagger() to deserialize the embedded
base64+gzip spec and returns it as JSON.

46 paths, 42 schemas — agents and humans can now introspect the
full API surface without reading Go source.
