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.
