Turkish (tr_TR) translation generation fails while other languages work

Summary

Turkish (tr_TR) translation generation fails while other languages work

Steps to reproduce

1. Run translation generation for Turkish (tr_TR) via the UI or "./scripts/ai/gemini-translate.sh tr_TR".
2. 2. Observe the "Translation complete" notification.
3. 3. Check the output file in "translations/tr_TR.json".

Expected behavior

The translation should be generated successfully.

Root Cause:
"gemini-translate.sh" passes the full content of "en_US.json" (~228 KB, 3655 keys) as a shell argument to both "jq" and "curl". This exceeds the shell's "ARG_MAX" limit.

Other bundled languages (de_DE, etc.) appear to work because their ".json" files already exist in the "translations/" directory - they were never actually generated through this script on the user's machine.

Logs

Check gemini-translate.sh for ARG_MAX limit.

Should be fixed in the last update, if not let me know!

The fix resolves the ARG_MAX issue but the underlying problem remains. The script still sends the entire en_US.json in a single request. With Gemini 2.5 Flash, this causes the output to be truncated, returning invalid JSON — translation fails silently.

Original script output (v2.25.0):

ERROR: Gemini returned non-JSON output. Translation discarded — your existing tr_TR.json is untouched.

With 700-key chunks:

Translating 3878 keys in 6 chunks of 700...
  Chunk 1/6 (keys 0–699)...
  Chunk 1/6 done (merged keys: 700).
  Chunk 2/6 (keys 700–1399)...
  Chunk 2/6 done (merged keys: 1400).
  ...
  Chunk 6/6 done (merged keys: 3878).

I was able to complete the Turkish translation by splitting into 700-key chunks with retry logic for 429/503 errors. Submitted as PR #151.

I don't know how other models or languages behave, but for Turkish with Gemini 2.5 Flash, this was the only approach that worked. Sharing the modified script below as a reference.
