fix(llms): make debug logs removable by consumer bundles

[FayezBast]

What

Fixes a runtime failure in downstream bundles that remove console calls.

Replaces the bound console.debug logger in @page-agent/llms with a wrapper function, allowing minifiers to safely remove console calls without making the logger non-callable.

Adds a regression test that bundles the real source, removes console calls, executes the optimized bundle, and verifies that modelPatch still works.

Closes #621
