🎯 What: Extract logic from fix_env to smaller helper methods _parse_env_content, _resolve_assignments, and _write_env_securely.
💡 Why: Reduces cyclomatic complexity and improves readability of fix_env.py without changing behavior.
Verification: Verified by checking format using ruff format and ruff check, and full test execution via uv run pytest.
Result: Improved maintainability and modularity of the script.

PR Summary

Low Risk
Low risk refactor that restructures code without altering the heuristics or file-write strategy; main risk is accidental behavioral drift in .env parsing/writing.

Overview
Refactors fix_env.py by extracting .env parsing (_parse_env_content), TOKEN/PROFILE swap resolution (_resolve_assignments), and atomic secure write (_write_env_securely) out of fix_env() to reduce complexity while preserving the same output format and symlink/atomic-replace safeguards.

Updates pr_payload.json to reflect the refactor-focused title/branch and description.

📝 Info: Refactoring preserves error-path behavior correctly

The old fix_env() used a return statement inside the except OSError block to skip the success-print statements at the end of the function. The new _write_env_securely() returns True/False, and fix_env.py:132 gates the success messages with if _write_env_securely(new_content):. This is semantically equivalent — on OSError, False is returned and no success message prints; on success, True triggers the prints. The refactoring correctly preserves this behavior.

📝 Info: New private helpers are correctly excluded from all

The three new functions _parse_env_content, _resolve_assignments, and _write_env_securely are prefixed with _ (private convention) and are not added to __all__ at fix_env.py:6. This is correct — they are internal implementation details. All external callers (tests/test_fix_env.py:5, tests/test_security.py:8) only use the public API (fix_env, clean_val, escape_val).
