fix: ensureBasePath fallback, per-file maxCount, include %b in format

- ensureBasePath now catches git rev-parse failures and falls back to
  process.cwd() instead of rejecting (handles non-repo / shallow CI)
- handleGitLogInfo and flushGitLogBatch both guard ensureBasePath with
  try/catch for defense-in-depth
- batchGetChangelog removes --max-count (which limited globally across
  all pathspecs, not per-file) and truncates per-file in JS instead
- Add %b (body) to git log pretty format to match getChangelog() output
