// delete.ts — Delete a key's value from the vault
//
// Part of: .opencode/skills/templating-vault/scripts/
//
// Removes a key's value file. Respects write-once and owner restrictions.
// Optionally deletes recursively under a prefix.
//
// USAGE:
//   delete.ts --key <key> [--owner <id>] [--recursive]
//             [--config <path>] [--store-dir <path>]
//
// OUTPUT (stdout): JSON result
