Remove python_version from API payloads, use language_version

[KRRT7]

Summary

• Remove python_version from all API payloads (add_language_metadata, optimize, rank, optimization_review)
• Fix optimization_review to use current_language_support().language_version instead of hardcoded Python-only detection, so Java/JS/TS get their version populated correctly
• Update test_add_language_metadata.py to reflect the removal

Depends on codeflash-ai/codeflash-internal#2488 being deployed first — the backend validators resolve python_version from language_version for backward compatibility.

Test plan

• tests/test_add_language_metadata.py — 10 tests pass
• Verify against deployed backend with the backward-compat validators

PR Review Summary

Prek Checks

Fixed one issue: import platform was left behind in codeflash/api/aiservice.py after all platform.python_version() calls were removed. Committed and pushed the fix (commit 33d92809).

All prek checks now pass.

Code Review

SMALL PR — focused correctness check.

The changes are clean and correct:

• add_language_metadata (aiservice.py:62): Removing the python_version field is safe — the backend handles backward compatibility via language_version.
• optimize payload (aiservice.py:270): Same — clean removal.
• rank payload (aiservice.py:532): Previously used platform.python_version() hardcoded for Python, now correctly omitted.
• optimization_review payload (aiservice.py:840-841): This is the most important fix. Previously language_version was None for non-Python languages. Now it uses current_language_support().language_version, which correctly populates Java/JS/TS versions.

No bugs, security issues, or breaking API changes found.

Duplicate Detection

No duplicates detected. The language_version fix in optimization_review is a single call site — no parallel language modules needed updating.
