Install full Noetica dependencies for dev-mode start

[mdheller]

Summary

The macOS Phase 1 validation now reaches Next.js ✓ Ready, so noetica start is functioning as a foreground server. However, because the formula installs production-only npm dependencies while the CLI still runs next dev, Next.js auto-installs TypeScript-related dev dependencies on first start.

Observed during validation:

It looks like you're trying to use TypeScript but do not have the required package(s) installed.
Installing devDependencies (npm):
- typescript
- @types/node

This is not acceptable packaging hygiene for the installed Cellar payload.

This PR removes --omit=dev from the Noetica npm install step while Phase 1 still uses dev-mode Next startup.

Boundary

• noetica start remains foreground mode.
• No brew services path is introduced.
• No service-supervision change.
• Prophet Mesh remains deferred.

Follow-up

A later release-artifact path should switch Noetica from dev-mode runtime to a built production runtime and then remove dev dependency installation from the formula again.

Validation target

After merge:

brew update
brew reinstall sourceos-linux/tap/noetica
noetica start

Expected: no first-run TypeScript/devDependency auto-install; Next reaches ✓ Ready and remains foreground until Ctrl-C.
