This PR improves formatModelName() so that it can parse brand names correctly (e.g., deepseek -> DeepSeek, glm -> GLM) and can tolerate a single leading letter in version number (e.g., v3, k2, m2).

📝 Walkthrough

The model-name formatter now joins dotted versions with letter-prefixed components and applies explicit casing to DeepSeek and MiniMax. Documentation and tests add examples for additional model names and version formats.

Changes: Model name formatting

Layer / File(s) Summary
Letter-prefixed version pairing
src/utils/format-model-name.ts
The formatter accepts a one- or two-digit version token with an optional leading letter when joining it to a numeric version component.
Brand casing and model examples
src/utils/format-model-name.ts, test/format-model-name.test.ts
The formatter maps DeepSeek and MiniMax to explicit casing. Documentation and tests add examples for Gemini, Whisper, DALL·E, DeepSeek, GLM, Kimi, and MiniMax.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Review comments at @src/utils/format-model-name.ts:
- Line 22: Update looksLikePrefixedVersionComponent so quantization tokens
matching q followed by digits are excluded from version pairing, while
preserving the existing matching behavior for other tokens. Add a regression
test for llama-3.1-8b-instruct-q4_0 that confirms the version remains merged and
the quantization suffix is not formatted as Q4.0.
