fix(translator): preserve prompt_cache_key when translating Responses API requests
(#517) — prompt_cache_key is an account-affinity signal used by Codex for
prompt cache routing. Deleting it from the translated request prevented full
cache effectiveness. Removed delete from openai-responses.ts and
responsesApiHelper.ts cleanup blocks.
fix(combo): escape \n in tagContent so injected JSON string is valid (#515)
— omniModel tag content used template literal newlines (U+000A) which produce
unescaped newline chars inside a JSON string value. Replaced with literal \n
escape sequences for valid JSON injection in streaming SSE content chunks.
The Gemini API rejects JSON schemas containing the "optional" field, returning
"400: Cannot find field: optional". Added "optional" to UNSUPPORTED_SCHEMA_CONSTRAINTS
in geminiHelper.ts so it is recursively stripped before sending to upstream.
Also: update star history section in README — embed replaced with live link
since api.star-history.com was suspended by GitHub in March 2025.
Closes#244
- Skip tools with defer_loading=true when assigning cache_control
(Anthropic API rejects the combination with 400)
- Delete stale schemas.js that shadowed the .ts source, causing
missing cloudSyncActionSchema export
Fixes#215
