Manual `terraform-docs markdown .` was fragile — no injection markers,
no idempotency check, and no consistent formatting pipeline.
Add terraform-docs inject mode with BEGIN/END_TF_DOCS markers in the
README so `terraform-docs .` regenerates only the managed section.
Wrap the injected block with prettier-ignore directives to prevent
prettier from reformatting tables (which would break terraform-docs
--output-check).
Restructure Makefile with three targets:
- `docs`: regenerate terraform-docs + prettier format README
- `fmt`: docs + terraform fmt -recursive
- `check`: verify all docs/formatting are current (CI-friendly)
Add node (LTS) and prettier to .mise.toml for markdown formatting.
