v0.19.0

This release implements #77, #78, #79, and #80.

Added

• Typed multipart client operations expose request-local filename overrides,
  including builder setters and response variants. Overrides use OpenAPI wire
  names and support both byte and conservative string binary mappings.
• Generated clients retain every supported successful response representation.
  Additive methods expose alternate JSON/text/binary bodies, live binary chunks,
  and raw or parsed SSE without replacing existing preferred methods or the
  configured SSE reconnection transport. Different schemas at different success
  statuses receive explicit status-specific methods.
• OpenAPI Overlay 1.1 preprocessing supports ordered RFC 9535 JSONPath
  updates, copies, and removals. Configure generator.overlays or repeat
  --overlay; optional effective_spec/--effective-spec materializes the
  transformed document and participates in --check and --dry-run.
• Optional versioned bindings.json describes emitted model and HTTP-client
  symbols, exact signatures, source operation locations, and response modes.
  Enable generator.bindings_metadata or --bindings-metadata. The additive
  library API generate_all_with_bindings returns output and metadata while
  retaining the existing GenerationResult shape. Initial metadata coverage
  rejects dedicated configured streaming, server, and registry generation.

Fixed

• Effective-document validation and generated default server URLs now run after
  schema extensions and overlays, so preprocessing and generation agree.
• Alternate JSON response schemas remain reachable when models are pruned.
• Client method, argument, builder, and transport-variant names share allocation,
  including collisions involving body parameters and filename overrides.

Breaking changes

Library API

• GeneratorConfig, configuration generator sections, SchemaAnalysis, and
  OperationResponse gained public fields for preprocessing, metadata, source
  locations, and complete response representations. Downstream exhaustive struct
  literals must include those fields. Prefer default-based configuration and
  construct analyses with SchemaAnalyzer.
