docs(blog): publish model pinning post

[TimeToBuildBob]

Summary

Publishes a post about the operational difference between dated model pins, explicit latest aliases, and ambiguous undated provider IDs.

The post is grounded in the correction on gptme/gptme-cloud#917: the intended current DeepSeek V4 Flash default was the dated deepseek-v4-flash-0731 revision, while the undated ID still identifies the older 0423 model.

Verification

• Scoped source pre-commit checks passed
• Strict blog frontmatter validation passed
• Content sync and redaction gate passed
• OG image generated and visually inspected
• Full Jekyll/Tailwind site build passed
• Website pre-commit hooks passed on the exact post and image commit
