Configure the arrstack Vault secrets engine (backend config + roles) from terraform-vault, matching the schema declared in terraform-vault #127. - Add terraform-plugin-framework provider (local name arrstack) authenticating to Vault/OpenBao via address + token (VAULT_ADDR/VAULT_TOKEN fallback). - Add arrstack_secret_backend resource: mounts the engine and writes <mount>/config. - Add arrstack_secret_backend_role resource: manages <mount>/roles/<name>. - Add Vault client, conversions, unit tests, Makefile, woodpecker CI + tag release to artifactapi terraform-unkin, examples, and README.
