fix(shared): normalize claude model IDs for anthropic provider (#3290)
Anthropic API accepts claude-opus-4.6 (dot format) but not claude-opus-4-6 (dash format). Added anthropic case to transformModelForProvider to normalize dash-format model IDs before they reach the provider. Updated model config snapshots and test expectations to match the new dot-format output. 🤖 Generated with OhMyOpenCode assistance https://github.com/code-yeongyu/oh-my-opencode
