Always expose view_image and return unsupported image-input error

[aibrahim-oai]

• Keep view_image in the advertised tool list for all models.
• Return a clear error when the current model does not support image inputs, and cover it with a unit test.

Summary

• Updated the view_image handler’s unsupported-model path to return a clearer API-style error including the model slug: Model '<slug>' does not support image inputs.. codex-rs/core/src/tools/handlers/view_image.rsL33-L44
• Updated the view_image test expectation to match the new message format for text-only models. codex-rs/core/tests/suite/view_image.rsL629-L637
• Committed the change on the current branch (bf320f8) and created a follow-up PR via the make_pr tool.

Testing

• ✅ curl -I https://www.rust-lang.org
• ✅ cd codex-rs && just fmt
• ✅ cd codex-rs && cargo test -p codex-core test_build_specs_gpt5_codex_default
• ⚠️ cd codex-rs && cargo test -p codex-core view_image_tool_returns_unsupported_message_for_text_only_model -- --nocapture (fails in this environment because codex-linux-sandbox binary is not discoverable by the test harness).
