The alibaba-coding-plan provider (8 models) was silently dropped when
models.generated.ts was regenerated from models.dev in PR #2118. This
provider uses a proprietary DashScope endpoint not tracked by models.dev,
so regeneration removes it every time.
Add models.custom.ts for manually-maintained providers that don't exist
in models.dev. The model registry (models.ts) now merges both generated
and custom models at startup. Custom entries are additive and never
overwrite generated ones.
