Chore: update anthropic Models

[edwinjosechittilappilly]

This pull request updates the list of Anthropic models in anthropic_constants.py to reflect the latest available models, clarify which are deprecated, and improve how deprecated and unsupported models are represented. The most important changes are:

New Model Additions:

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

Deprecation and Organization Improvements:

• Moved previously listed models (e.g., 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.
• Marked older models without tool calling support (claude-2.1, claude-2.0) as deprecated and moved them to the deprecated section for clarity.

Cleanup and Clarity:

• Removed redundant or outdated entries, and reorganized the order to separate active, deprecated, and unsupported models more clearly.

Walkthrough

This pull request updates the Anthropic model constants by adding two new models (claude-opus-4-5-20251101 and claude-haiku-4-5-20251001), removing four model variants, marking multiple models as deprecated, and adjusting tool_calling capabilities across the catalog.

Changes

Cohort / File(s)	Summary
Anthropic model configuration src/lfx/src/lfx/base/models/anthropic_constants.py	Added new Anthropic models with updated capabilities; removed legacy model entries; deprecated four model variants; adjusted tool_calling flags for multiple models; reconfigured model catalog to reflect current Anthropic offerings

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify new model identifiers (claude-opus-4-5-20251101, claude-haiku-4-5-20251001) match current Anthropic API
• Confirm tool_calling capability flags align with Anthropic's actual model specifications
• Validate that deprecated models are correctly marked and correspond to Anthropic's official deprecation schedule

Check name	Status	Explanation	Resolution
Test Coverage For New Implementations	❌ Error	No test files were added or modified to validate changes to anthropic_constants.py model configurations.	Add test file (e.g., test_anthropic_constants.py) to validate new models, deprecated flags, and tool-calling capabilities are correctly configured.
Test Quality And Coverage	⚠️ Warning	PR updates Anthropic model constants but lacks test coverage validating new models, deprecated flags, and tool_calling configurations.	Add pytest tests validating new model configurations, deprecated flags, tool_calling capabilities, and preventing regressions in model constants.
Test File Naming And Structure	❓ Inconclusive	Modified anthropic_constants.py lacks accompanying unit tests following test_*.py naming convention despite test infrastructure present.	Create dedicated test file test_anthropic_constants.py with tests verifying model configurations, deprecation flags, and tool-calling capabilities.

The model 'claude-3-5-haiku-20241022' appears in both the active models section (line 11) and the deprecated models section (line 39). This duplication could lead to confusion and inconsistent behavior. Remove one of these entries based on the model's actual status.
