Subpackages source code changes (Plugins, Marketplace, Core, etc.) not reflecting globally during development

[cuchakma]

When we change code in sub-packages, the UI doesn't update automatically — we have to manually run pnpm run build from the CMS root folder every time. Is there a single command we can run once, that will automatically detect and apply changes from any source folder, without needing to rebuild everything manually each time?

There's no single root-level watch command right now — no turbo.json in the repo, and the root package.json has no dev/watch script. The documented flow (see CONTRIBUTING.md) is one terminal per package you're actively editing:

# Terminal 1
cd packages/core && pnpm dev   # tsdown --watch
# Terminal 2
cd demos/simple && pnpm dev    # astro dev, picks up the watched output via workspace:*

Each package defines its own "dev": "tsdown --watch" (or similar). Once each watcher is running, changes do propagate to the site automatically — it's just per-package rather than a single repo-wide command, so editing core + a plugin at once means a terminal for each.
