feat(anthropic): update model YAMLs [bot]

[models-bot]

Auto-generated by poc-agent for provider anthropic.

---

Note

Low Risk
Single metadata field on a model catalog YAML; no runtime or API behavior change.

Overview
Adds retirementDate: "2027-02-17" to providers/anthropic/claude-sonnet-4-6.yaml, aligning claude-sonnet-4-6 with other Anthropic model configs that already declare a retirement date. No changes to pricing, limits, params, or status (still active).
