 * Generates `src/cli/src/config/opencode-extension.ts`, which embeds the two
 * opencode plugin sources as string constants — mirroring how the pi extension
 * (`pi-extension.ts`) and prime-agent's `/mcpctl` switcher
 * (`prime-agent-extension.ts`) are embedded.
 *
 * Embedding matters: `mcpctl config opencode` must work from an installed
 * binary that has no access to the source tree. The installed plugin files are
 * this exact embedded source, so what the CLI ships is always what opencode
 * runs.
 *
 * Regenerate after editing the plugin sources:
 *   npx tsx scripts/generate-opencode-extension.ts
