feat(models): add quantization to novita meta mappings

[AmineAce]

Adds quantization to Novita provider mappings in packages/models/src/models/meta.ts, per #2946.
Checked every Novita mapping in this file against Novita's own model detail pages. Added the field only where precision was explicitly stated, no inference from model names.

llama-3.1-8b-instruct → fp8
llama-3.3-70b-instruct → bf16
llama-4-scout-17b-16e-instruct → bf16
llama-3.2-3b-instruct → bf16

Left unchanged, llama-3-8b-instruct and llama-3-70b-instruct no longer exist on Novita's site (404 on their model page), likely retired from their catalog.
Ran pnpm format; only this file changed.

Summary by CodeRabbit

• New Features
  • Added quantization details to several model listings, including updated support for select Llama models.
  • Improved model metadata so compatible variants can be identified more accurately during selection.
