Goal

Boot QuickNotes inside a Vagrant VM, snapshot the working state, and restore from it.

Changes

• Add Vagrantfile at repo root (Ubuntu 24.04, Go 1.24.5, port 18080→8080, 2 vCPU / 1024 MB)
• Add submissions/lab5.md covering Task 1 (Vagrantfile + curl proofs) and Task 2 (snapshot lifecycle + design questions)

Testing

• vagrant up provisions Go 1.24.5 and passes idempotency check on re-provision
• curl http://localhost:18080/health from host returns {"notes":13,"status":"ok"}
• Snapshot saved → Go wiped → go version returned exit 127 → snapshot restored → go version go1.24.5 linux/amd64
• Restore timed at 23.5 s via Measure-Command { vagrant snapshot restore clean-go-install }
