git_tools: improve commit range selection when fewer than 10 commits exist

Replace hardcoded fromCommit~10 check with flexible loop that tries
offsets from 10 down to 0, selecting the first valid range.

Problem Analysis:
The getGitLog function was failing when repositories had fewer than
10 commits total. It attempted to check if fromCommit~10 existed and
fell back to fromCommit..HEAD only if that check failed, causing
issues in new repositories or shallow clones.

Implementation Changes:
- Added loop from i=10 down to i=0 to find the largest valid offset
- Use git rev-parse --verify to test each fromCommit~i combination
- Fall back to fromCommit..HEAD when no offset works (i=0 case)
- Maintain same git log command structure and output format

Benefits:
- Works correctly with repositories of any size
- Gracefully handles edge cases like single commits
- Maintains existing functionality for larger repositories
- No changes to function signature or return format

Testing:
All existing tests continue to pass, confirming backward compatibility.
