Model catalog schema gains effort-level, family, and image-limit fields

What

• The model definition schema used in the model catalog now accepts new fields: effort_levels, default_effort, capabilities, family, knowledge_cutoff, default_for_family, fast_default_for_family, and image_limits (with max_width/max_height).
• These fields are defined in a new schema (referenced as runtime inside a larger model-catalog entry schema) alongside existing fields like notice, selection_notice, badge, tooltip, and quick_select, and also include max_input_tokens/max_output_tokens.

Why These fields let the model catalog describe, per model, which effort levels are available and the default one, which family a model belongs to and whether it's that family's default, and image size limits — metadata Claude Code can use to present and select models more accurately.
