convertOpenAIToolChoice mapped {type:"function"} verbatim and cloakClaudeTools
left tool_choice.name unsuffixed, both rejected by Claude on the cc/ path.
Map forced-function to {type:"tool",name}, allowlist Claude-valid types, and
suffix tool_choice.name when it targets a renamed client tool.
Fixes#1592

- github.js: split thinking vs reasoning_effort stripping
- thinking (Claude-native format) still stripped for all Claude on Copilot
- reasoning_effort now passed through for Opus 4.6 and Sonnet 4.6
- still stripped for Haiku 4.5 and Opus 4.7 (rejected upstream)
- reasoning_effort "none" stripped for all models (not all support it)
- openai-to-claude.js: map reasoning_effort → thinking.budget_tokens
for direct Anthropic backend (none→skip, low→4096, medium→8192,
high→16384, xhigh→32768)
Previously reasoning_effort was stripped for ALL Claude models,
meaning Opus 4.6 via Copilot never received thinking configuration.

- Add claudeHeaderCache.js to intercept and cache live Claude Code client headers
- Forward cached headers dynamically to api.anthropic.com via default.js
- Strip first-party identity headers (x-app, claude-code-* beta) for non-Anthropic upstreams
- Validate and sanitize tool call IDs to match Anthropic pattern (^[a-zA-Z0-9_-]+$)
- Skip thinking blocks when applying cache_control; fix max_tokens buffer (+1024)
- Strip cache_control from thinking blocks in openai-to-claude translator
- Comment out thoughtSignature in Gemini translator (kept for reference)
- Expand .gitignore to match all deploy*.sh variants

Closes#433
Made-with: Cursor
Previously only base64 data: URLs were handled in the OpenAI-to-Claude
and OpenAI-to-Gemini request translators. HTTP/HTTPS image URLs were
silently dropped, causing vision-capable models to respond with
"I don't see any image."
Translates OpenAI response_format parameter into Claude-compatible system
prompt instructions, enabling structured JSON output for json_schema and
json_object types.

Made-with: Cursor
- Added handling for HTTP_STATUS.NOT_ACCEPTABLE in error types and messages.
- Enhanced the `prepareClaudeRequest` function to filter built-in tools for non-Anthropic providers and clean up empty tool arrays.
- Updated the `openaiToClaudeRequest` function to handle built-in tools more effectively and ensure proper tool conversion.
- Improved the `claudeToOpenAIResponse` function to skip processing for built-in server tool blocks.
- Refined error message handling in the `parseUpstreamError` function to ensure meaningful output.
- Adjusted command checks for tool installations across various settings routes to use `command -v` for better compatibility.
Preserve thinking configuration when converting OpenAI requests to Claude format.
- Handle thinking.type with 'enabled' as default
- Preserve thinking.budget_tokens when present
- Preserve thinking.max_tokens when present
This enables proper thinking mode support for o1-series models
when routed through 9Router to Claude endpoints.
