* fix: prevent system package removal during Ubuntu dependency install
This PR fixes a critical issue where installing agent-browser dependencies on Ubuntu 24.04+ could trigger removal of hundreds of system packages due to library naming conflicts during the 64-bit time_t transition.
**Problem:**
On Ubuntu 24.04+, many core libraries were renamed with a "t64" suffix as part of the 64-bit time_t transition. The installer was trying to install old library names, causing apt to propose removing 400+ essential system packages to resolve conflicts.
**Changes:**
- Added comprehensive t64 variant detection for all apt dependencies
- Implemented pre-install simulation check to detect potential package removals
- Added safety abort mechanism when removals are detected (>0 packages)
- Enhanced error messaging to explain the issue and provide manual installation guidance
- Improved logging and user feedback during the installation process
**Implementation Details:**
- Uses `apt-get install --simulate` to safely check for conflicts before proceeding
- Checks for t64 variants first, falls back to original names if t64 versions don't exist
- Provides detailed output showing which packages would be removed
- Maintains compatibility with older Ubuntu versions that don't have t64 packages
Fixes#881
* refactor: extract duplicate install status handling into helper
