Compact-cache fallback now preserves abort behavior instead of continuing through fallback paths after cancellation. Evidence: abort checks added around compact cache sharing (search for "Compact cache sharing: no text in response, falling back").
Windows command/path handling gained additional normalization and quoting safeguards for daemon spawning, including rejection of unsupported Unicode single-quote variants in generated PowerShell command lines.
