Need to handle mods with code compilations errors on build and load

Summary

I built a mod, but while the cmd mods list showed it as available in the project, the command it had did not appear.

Turns out there was a compilation issue, but I had no way of knowing:

 in the @.commandcode/mods/erd.ts there should be comands but i have reloaded but i dont see them available. but i see it is available cmd mods list

  Built-in mods (4)
    provider-anthropic · builtin
    provider-copilot · builtin
    provider-openai · builtin
    update-notice · builtin

⠶ Let me look at your mod file and check the Command Code mod docs to figure out why the commands aren't appearing.

 READ  [.commandcode/mods/erd.ts] 1011 lines

⠶ Let me check if there's a TypeScript compilation issue or missing dependency.

✻ Thought for 29 seconds [ctrl+o to expand]

⠶ Found the issue. The regex on line 115 has an unmatched parenthesis — the capture group ( is never closed, making the regex invalid. This causes the mod to fail
  to load entirely, which is why /cmd mods list shows it but none of its commands appear.

Expected Behavior

• the mod builder should run some type or compile checks
• on load of the mod, warn that a mod failed to load so can correct (or status of disable due to error)
• something to know while mod isn't working/available

Actual Behavior

• mod listed but commands it implements not present

Steps to reproduce the issue

• use mod builder but introduce some type or build compilation error in it

Reproduce el fallo usando la expresión regular malformada indicada en la línea 115 de .commandcode/mods/erd.ts, y luego rastrea cómo el constructor de mods y cmd mods list gestionan la carga fallida. Se considera terminado cuando los errores de compilación o de carga se muestran claramente y el estado no disponible o deshabilitado del mod es visible, en lugar de mostrarlo como utilizable.
