/**
 * Generates `src/cli/src/config/prime-agent-extension.ts`, which embeds the
 * prime-agent `/mcpctl` switcher as a string constant — the same arrangement
 * the pi and opencode extensions use.
 *
 * The switcher used to live *only* as that string literal, with no source file
 * behind it, so nothing typechecked or linted it. Now `src/prime-agent-ext/`
 * holds the real source and this script produces the embed, so the file the CLI
 * writes into ~/.prime/agent/extensions/ is always exactly what was checked.
 *
 * Regenerate after editing the extension source:
 *   npx tsx scripts/generate-prime-agent-extension.ts
