Subject: [PATCH] Add Claude Sonnet 4.5 model support

- Register `claudeSonnet45Api` with the Anthropic API list using the
  `claude-sonnet-4-5-20250929` identifier.
- Add OpenRouter (`anthropic/claude-sonnet-4.5`) and AIML
  (`anthropic/claude-sonnet-4-5`) options to keep providers in sync.
- Update the default OpenRouter model to Sonnet 4.5 so new installs use
  the latest Claude Sonnet model.
