`6462ab9` feat(openai): add web search tool support for Responses API (#173)

Click to expand commit body

Add OpenAI web search as a provider-defined tool, mirroring the
Anthropic web search implementation pattern.

New files:
- providers/openai/web_search.go: WebSearchTool() helper with
  SearchContextSize, AllowedDomains, and UserLocation options.
- examples/openai-web-search/main.go: Example using the agent
  pattern with web search.

Changes to existing files:
- responses_options.go: WebSearchCallMetadata, WebSearchAction,
  and WebSearchSource types registered for JSON round-tripping.
- responses_language_model.go:
  - toResponsesTools(): Route ProviderDefinedTool web_search to
    the OpenAI SDK WebSearchToolParam.
  - Generate(): Emit ToolCallContent + ToolResultContent pair for
    web_search_call output items. Source citations come from
    url_citation annotations on message text.
  - Stream(): Emit ToolInputStart/ToolInputEnd/ToolCall/ToolResult
    lifecycle events for web_search_call items.
  - toResponsesPrompt(): Round-trip provider-executed tool calls
    via item_reference; skip SourceContent and provider-executed
    ToolResultPart (already handled by the reference).
- providertests/provider_registry_test.go: Add metadata test case.

`eaa111e` chore(anthroipic): harden web_search coercion for json round-trips

Click to expand commit body

This guards against cases when web_search options could be silently
dropped when tool args pass through generic/JSON-shaped data, so domain
filters, max uses, and user location reliably reach Anthropic.

`38eb77b` feat: add Anthropic web search tool support (server_tool_use + web_search_tool_result)

Click to expand commit body

- Handle ProviderDefinedTool with ID "web_search" in toTools(), mapping to
  anthropic.WebSearchTool20250305Param with optional allowed/blocked domains
- Parse "server_tool_use" blocks in Generate() and Stream(), producing
  ToolCallContent with ProviderExecuted=true
- Parse "web_search_tool_result" blocks, extracting SourceContent for each
  search result and a ToolResultContent summary
- Stream server_tool_use via ToolInputStart/ToolInputEnd/ToolCall events
- Stream web_search_tool_result via Source events for each result item
- Skip provider-executed tool results and source content when building
  Anthropic prompts (toPrompt) to avoid sending unrecognized block types
- Add ProviderExecuted field to ToolResultPart with JSON marshal/unmarshal
- Propagate ProviderExecuted from ToolResultContent to ToolResultPart in
  agent's toResponseMessages()

`a3b8a69` fix(openrouter): preserve anthropic reasoning signature in streaming

Click to expand commit body

Anthropic sends the reasoning signature chunk after tool_calls have
started. The streaming hook was ending reasoning prematurely on the
first tool_call chunk, so the late-arriving signature was lost. Track
the reasoning format and defer ending for anthropic streams until the
signature arrives. Also fix the agent stream assembler to not overwrite
provider metadata with nil on reasoning deltas.

`152acfe` fix: guard against nil EncryptedContent dereference in reasoning details

Click to expand commit body

Reasoning metadata can exist without encrypted content, causing a nil

`7dc3888` fix(openrouter): don't set User-Agent

Click to expand commit body

OpenRouter rejects API calls using a custom User Agent. This workaround
skips OpenRouter when setting a user agent.

Note that we've added two new methods accordingly, as OpenRouter uses
the openai package:

openai.WithSkipUserAgent()
openai.WithLanguageModelSkipUserAgent()
