- Enforce stream_read timeout (30s default) in all 4 providers' streaming code
- Add with_timeout() builder method to all adapter constructors
- Fix ResponseFormatType::JsonObject to serialize as "json" per spec
- Add STEP_FINISH to StreamEventType enum in spec doc
- Add UnsupportedToolChoice error and enforce in all adapters via validate_tool_choice()
- Fix error classification to check status code before message content
- Add stop_sequences support to OpenAI Responses API adapter
- Handle Gemini thought parts (thought: true) in both complete and streaming paths

- OpenAI adapter: include is_error flag on function_call_output items
- Anthropic adapter: extract retry_after from headers in streaming error path
- Error retryability: unknown errors now default to retryable per spec
- stream_object: add ObjectStreamResult wrapper with object() accessor
- TimeoutConfig: add From<f64> for total-only timeout shorthand
- Message::tool_result: accept serde_json::Value to preserve structured content
- GenerateParams: expose repair_tool_call field wired to execute_all_tools_with_repair
- Both generate() and stream() tool loops use repair-aware execution

- Anthropic adapter estimates reasoning_tokens from thinking block text lengths
- Add tool call validation against JSON schema + repair_tool_call callback
- Call adapter.initialize() on provider registration
- Extract model catalog to catalog.json data file loaded via include_str!
- Add ContentPart::Other variant for unknown/extensible content kinds
- Change StreamEvent::Error field from String to SdkError
- Add ToolContext (tool_call_id, messages, abort_signal) to execute handlers
- Gemini adapter uses gRPC status codes from error bodies for classification

- Add Audio/Document content part handling across all providers:
Anthropic supports documents natively, Gemini supports both audio
and documents, OpenAI and OpenAI-compatible produce text fallbacks
- Add stop_when support to streaming tool loops (was only in generate())
- Add retry on initial stream connection (matching generate() behavior)
- Add total and per_step timeout support to streaming tool loops

Add StepFinish stream event variant emitted between tool execution steps
during streaming, matching spec section 5.9. Add OPENAI_ORG_ID and
OPENAI_PROJECT_ID env var support with corresponding HTTP headers. Add
default_headers builder method to all four provider adapters for custom
header injection in programmatic setup.

- Anthropic: Add response_format support via tool-based extraction (JsonSchema
injects synthetic tool, JsonObject appends system prompt instruction)
- Anthropic: Pass Request.metadata through to Messages API
- Anthropic: Refactor complete()/stream() to share build_api_request()
- Gemini: Parse rate limit headers from HTTP responses in complete() and stream()

- Add abort signal support using CancellationToken for cooperative cancellation
of generate() and stream() calls
- Fix max_tool_rounds=0 to skip tool execution entirely (was executing first round)
- Add StreamResult wrapper with response(), text_stream(), partial_response()
and multi-step tool loop support in high-level stream()
- Add OpenAI metadata and provider_options.openai pass-through to Responses API
- Add Gemini provider_options.gemini pass-through (safety settings, cached content)
- Add OpenAI-compatible provider_options.<name> pass-through using adapter name

- Parse x-ratelimit-* headers into RateLimitInfo for Anthropic, OpenAI, and
OpenAI-compatible providers (previously hardcoded to None)
- Add "not found"/"does not exist" and "unauthorized"/"invalid key" error
message classification patterns for ambiguous HTTP status codes
- Apply TimeoutConfig.total to wrap the entire multi-step generate() loop
(previously only per_step was used)
- Add metadata field to GenerateParams with builder method, pass through to
Request instead of hardcoding None
- Implement stream_object() for streaming structured output with incremental
JSON parsing via new ObjectStreamEvent type (Partial/Delta/Complete variants)
- Add OpenAI-compatible Chat Completions adapter for third-party endpoints

Extract shared provider helpers (parse_error_body, send_and_read_body,
extract_system_prompt, ApiMessage) into providers/common.rs, eliminating
duplicated logic across all three providers. Simplify StepResult and
GenerateResult to derive fields from the embedded Response rather than
storing redundant copies. Remove stringly-typed ToolCall.r#type and
ResponseFormat.r#type in favor of proper enums. Remove unused dependencies
(hyper, clap, rayon, base64, etc.), use LazyLock for the model catalog,
and fix miscellaneous idiom issues (unnecessary Vec collects, inconsistent
error Display, module_name_repetitions).

Enable clippy::all, pedantic, nursery, and cargo lint groups at the
workspace level. Fix all resulting warnings: merge identical match arms,
add #[must_use] and doc sections, derive Eq, use clone_from, add type
alias for complex types, extract helpers to reduce function length, and
add crate metadata.
