fix(archsetup): implement critical bug fixes and test improvements

This commit addresses several high-priority bugs and enhances the testing infrastructure:

**Bug Fixes:**
1. Add root permission check at script start to fail fast with clear error message
2. Disable debug package installation by adding --nodebug flag to all yay calls
3. Replace unsafe `git pull --force` with safe rm + fresh clone to prevent data loss
4. Add geoclue package with correct systemd service configuration for geolocation
5. Add completion marker for reliable automated test detection

**Testing Infrastructure:**
- Add comprehensive VM-based testing framework in scripts/testing/
- Fix test script pgrep infinite loop using grep bracket self-exclusion pattern
- Add network diagnostics and pre-flight checks
- Support snapshot-based testing for reproducible test runs

**Package Management:**
- Remove anki (build hangs 98+ minutes)
- Remove adwaita-color-schemes (CMake build issues)

Test Results: 0 errors, 1,363 packages installed in 40 minutes
