Translator path guard blocks Claude tool id sanitization follow-up #1930
Description
Summary
The current PR path guard blocks any pull request that modifies internal/translator/**.
I originally prepared a PR to sanitize Claude tool ids and preserve tool mappings across translator paths, but the ranslator-path-guard workflow fails immediately for those file changes.
Requested maintenance work
Please consider applying the following translator-side changes internally:
- sanitize provider-facing Claude ool_use.id values to satisfy ^[a-zA-Z0-9_-]+$
- preserve original ool_use.name mappings when translating Claude request/response payloads
- add regression coverage for Antigravity, Gemini CLI, Gemini, Codex, and OpenAI Claude-compatible paths
Context
Related public PR: #1927
That PR has now been narrowed to reusable helper functions under internal/util/** so it can comply with the repository path guard.
