fix: prevent bypassing .rooignore restrictions via terminal commands

- Updated error message when files are blocked by .rooignore to explicitly warn against using terminal commands to bypass restrictions
- Added clear instructions in .rooignore system prompt to not attempt bypassing restrictions
- Updated tests to verify the new warning messages are included

Fixes #7204
