Start HTTP Registry Server

Start the http-registry server in the background.

Instructions:

1. First, find the monorepo root (working directory may have drifted):

   git rev-parse --show-toplevel
   

2. Run the command with run_in_background: true, prefixing with cd to the monorepo root:

   cd <MONOREPO_ROOT> && pnpm -C typescript/infra start:http-registry
   

3. After starting, report the task/shell ID to the user
4. Remind the user they can stop it later with KillShell using that ID
5. Note the URL that the registry is running on, which would be http://localhost:<port>, where the port can be found in the logs.

Example output:

Started http-registry server in background (shell ID: shell_abc123). To stop it later, I can use KillShell or you can run /stop-http-registry.
