Undo a terraform apply by snapshotting state before each apply and restoring on demand.
How it works
Before every apply the extension runs terraform state pull and saves the state JSON to a local .tf-undo/ directory. On undo it pushes the saved state back with terraform state push -force and re-runs terraform apply so infrastructure is reconciled back to the pre-apply configuration.

Notes
Add .tf-undo/ to your .gitignore — state files can contain sensitive data.
The undo dialog offers Undo Apply (push state + apply) or Push State Only (state push only, then you can inspect with terraform plan before applying).
Snapshots are trimmed automatically to maxSnapshots.
