// get.ts — Retrieve a value from the vault
//
// Part of: .opencode/skills/templating-vault/scripts/
//
// Reads a value by key. If the key is marked template: true, evaluates the
// Nunjucks expression lazily, resolving dependencies from the vault.
//
// USAGE:
//   get.ts --key <key> [--config <path>] [--store-dir <path>]
//   get.ts --prefix <prefix> [--config <path>] [--store-dir <path>]
//
// With --prefix: returns all key-value pairs under the prefix.
//
// OUTPUT (stdout): JSON result
// =============================================================================
