Package CodeNomad OpenCode plugin (#433)

## Summary - Rename the OpenCode config template into a versioned npm-packable CodeNomad plugin package. - Build and package the plugin through the server bundle, with Electron/Tauri carrying it via existing server resources. - Replace OPENCODE_CONFIG_DIR injection with JSONC-aware OPENCODE_CONFIG_CONTENT merging that appends the CodeNomad plugin while preserving user config. ## Validation - npm run build --workspace @codenomad/codenomad-opencode-plugin - npm run prepare-plugin --workspace @neuralnomads/codenomad - npm run typecheck --workspace @neuralnomads/codenomad - npm run typecheck --workspace @neuralnomads/codenomad-electron-app - node --import tsx --test \"src/opencode-plugin.test.ts\" \"src/workspaces/__tests__/spawn.test.ts\" ## Notes - Production plugin loading uses an explicit npm file alias for the packaged tarball. - Dev loading still references the TypeScript plugin entry directly. --------- Co-authored-by: Pascal André <pascalandr@gmail.com>

-# opencode-config
+# CodeNomad OpenCode Plugin

 ## TLDR
-Template config + plugins injected into every OpenCode instance that CodeNomad launches. It provides a CodeNomad bridge plugin for local event exchange between the CLI server and opencode.
+Packaged OpenCode plugin injected into every OpenCode instance that CodeNomad launches. It provides the CodeNomad bridge for local event exchange between the CLI server and OpenCode.

 ## What it is
-A packaged config directory that CodeNomad copies into `~/.config/codenomad/opencode-config` for production builds or uses directly in dev. OpenCode autoloads any `plugin/*.ts` or `plugin/*.js` from this directory.
+An npm-packable plugin package. Production builds ship a local `.tgz` and inject it through `OPENCODE_CONFIG_CONTENT`; dev runs reference the TypeScript plugin entry directly with a `file://` URL.

 ## How it works
- CodeNomad sets `OPENCODE_CONFIG_DIR` when spawning each opencode instance (`packages/server/src/workspaces/manager.ts`).
- This template is synced from `packages/opencode-config` (`packages/server/src/opencode-config.ts`, `packages/server/scripts/copy-opencode-config.mjs`).
- OpenCode autoloads plugins from `plugin/` (`packages/opencode-config/plugin/codenomad.ts`).
- The `CodeNomadPlugin` reads `CODENOMAD_INSTANCE_ID` + `CODENOMAD_BASE_URL`, connects to `GET /workspaces/:id/plugin/events`, and posts to `POST /workspaces/:id/plugin/event` (`packages/opencode-config/plugin/lib/client.ts`).
+- CodeNomad sets `OPENCODE_CONFIG_CONTENT` when spawning each OpenCode instance (`packages/server/src/workspaces/manager.ts`).
+- The server packs this package during build (`packages/server/scripts/package-opencode-plugin.mjs`).
+- OpenCode loads the plugin from `plugin` entries injected into the config content.

 - The server exposes the plugin routes and maps events into the UI SSE pipeline (`packages/server/src/server/routes/plugin.ts`, `packages/server/src/plugins/handlers.ts`).
