fix(nano-gpt): rename bundled confirmed 2-suffix model ids

[sk0x0y]

Summary

• rename the remaining NanoGPT 2/* catalog entries with exact confirmed canonical replacements
• keep this PR limited to families whose live NanoGPT API ids match the same path after dropping the 2 suffix
• validate the updated catalog with bun run validate

Included families

• EVA-UNIT-01
• Envoid
• GalrionSoftworks
• Gryphe
• Infermatic
• LLM360
• LatitudeGames
• MarinaraSpaghetti
• NeverSleep
• Sao10K
• Steelskull
• VongolaChouko

Why

• models.dev derives NanoGPT model ids directly from file paths in packages/core/src/generate.ts
• OpenAI-compatible clients must send the exact id returned by the provider's models API
• for every family in this PR, the canonical public NanoGPT id is the same path with only the 2 suffix removed
• keeping the old 2/* paths makes copied ids fail in direct usage

Scope and exclusions

• this PR includes only exact drop-2 replacements confirmed by the live NanoGPT API
• it intentionally excludes ambiguous families such as NousResearch 2/* and TheDrummer 2/*, which need separate casing validation
• this PR is path-only and does not change model metadata outside the namespace correction

Verification

• bun run validate passes
• all renamed canonical ids are present in the catalog and confirmed by the live NanoGPT API
