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

Command Code Version

1.5.0

Operating System

Additional context

No response

Reproduce the failure using the malformed regex reported at line 115 of .commandcode/mods/erd.ts, then trace how the mod builder and cmd mods list handle the failed load. Done means compilation or load errors are surfaced clearly and the mod's unavailable or disabled status is visible instead of listing it as usable.
