Re-enable FreeBSD CI/CD testing when VM reliability improves

[aygp-dr]

Description

The FreeBSD VM testing in GitHub Actions has been temporarily disabled due to reliability issues. The VM often fails to boot or takes excessive time (5+ hours) to complete simple tasks.

Current Status

• FreeBSD testing has been replaced with a Linux-based compatibility check
• The Linux job simulates FreeBSD environment as much as possible
• See .github/workflows/deps.yml for the commented out FreeBSD VM configuration

Tasks

• Monitor vmactions/freebsd-vm for stability improvements
• Test FreeBSD VM reliability periodically
• Re-enable FreeBSD-specific CI when stable
• Consider alternative FreeBSD CI solutions (CircleCI, BuildJet, etc.)

Notes

SEFACA is optimized for FreeBSD, so native FreeBSD testing is important for the project's long-term quality assurance.
