Fixed safe-flag parsing for combined short flags in commands like grep and rg (e.g., -A5 is now correctly recognized as -A with value 5 when -A accepts a number) (search for "grep" and "rg" in function Hn7)
Improved Remote Control error messaging: users on unsupported plans now see "Error: Remote Control is not yet available on your plan." (search for "Remote Control is not yet available")
Fixed line-reference edit operations to properly validate hash mismatches with clear error messages showing expected vs actual hash, preventing silent corruption when files change between reads (search for "LINE#HASH")
