Install this agentproto app

What this does

Registers this directory's .agentproto/APP.md-defined app with the local
agentproto CLI, so the daemon (agentproto serve) can resolve it by id.
This skill is intentionally generic — it does not read or care about
whatever this particular bundle declares (book, kit, dashboard…); it only
shells out to the one CLI verb every agentproto app installs through.

Steps

1. Confirm agentproto is installed and on PATH:

   agentproto --version

   If it isn't, install it first — npm i -g @agentproto/cli, or whatever
   this bundle's own README recommends.

2. From this directory (the one containing .agentproto/APP.md), run:

   agentproto app install .

   This reads the app's id from .agentproto/APP.md and registers
   id -> this directory in ~/.agentproto/apps.json — the same mapping
   the daemon's app_install tool writes. Re-running it for the same id
   is safe (idempotent): it updates the existing entry rather than erroring.

3. Make sure the daemon is running (skip if it's already up, e.g. as a
   background service):

   agentproto serve

4. The app is now installed. What "using" it looks like from here depends
   on the client — the daemon's app_* MCP tools (app_run, app_apply,
   app_status, …), or agentproto app serve . for a standalone browser
   view, are both fair game. This skill's job stops at "installed and
   registered."

Gotchas

• agentproto app install needs a .agentproto/APP.md in the target
  directory (an app dir, not an arbitrary folder) — run it from the app's
  root, or pass that root as the argument instead of ..
• Installing an app is not the same as running it — this skill covers
  registration only.
