fix: anthropic constants

[edwinjosechittilappilly]

This pull request updates the list of Anthropic models in anthropic_constants.py to include new model versions, clarify which models are deprecated, and reorganize the list for better clarity. The main changes are the addition of new models, explicit marking of deprecated models, and improved grouping of models by their status.

Model updates and additions:

• Added new Anthropic models: claude-opus-4-5-20251101, claude-haiku-4-5-20251001, claude-3-5-haiku-20241022, and claude-3-haiku-20240307 as supported models with tool calling enabled.

Deprecation and organization:

• Moved previously listed models (claude-3-7-sonnet-latest, claude-3-5-sonnet-latest, claude-3-5-haiku-latest, claude-3-opus-latest) to a new "Deprecated models" section and explicitly marked them as deprecated.
• Updated legacy models claude-2.1 and claude-2.0 to be marked as deprecated and grouped them under deprecated models, clarifying their tool calling support as false.
• Reorganized the model list to clearly separate currently

The model claude-3-5-haiku-20241022 was previously marked as deprecated but is now listed as a currently supported model. This appears inconsistent with claude-3-5-sonnet-20241022 (line 39) which remains deprecated. If this model is being un-deprecated, please verify this is correct. If both models were released around the same time (October 2024), it's unclear why one would be deprecated and the other not.

Suggested change

	create_model_metadata(provider="Anthropic", name="claude-3-5-haiku-20241022", icon="Anthropic", tool_calling=True),
	create_model_metadata(provider="Anthropic", name="claude-3-5-haiku-20241022", icon="Anthropic", tool_calling=True, deprecated=True),

The model claude-3-haiku-20240307 was previously marked as deprecated but is now listed as a currently supported model. Given this model is from March 2024 (over 1.5 years old), it's unusual to un-deprecate it. Please verify this change is intentional and that this older model should indeed be actively supported.

Suggested change

	create_model_metadata(provider="Anthropic", name="claude-3-haiku-20240307", icon="Anthropic", tool_calling=True),
	create_model_metadata(provider="Anthropic", name="claude-3-haiku-20240307", icon="Anthropic", tool_calling=True, deprecated=True),
