 * Generates `src/cli/src/config/opencode-extension.ts` which embeds the opencode
 * plugin source (`open-mcpctl.tsx` + `projects.ts`) as string constants,
 * mirroring how the pi and prime-agent extensions 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 source:
 *   npx tsx scripts/generate-opencode-extension.ts
