Enhance EarlyStopping with mode and min_delta_mode parameters for imp…

[aaishwarymishra]

This pull request introduces significant improvements to the EarlyStopping handler in Ignite, adding support for both minimization and maximization modes, as well as absolute and relative thresholds for improvement. It also updates the documentation, validation logic, and expands test coverage to ensure correctness for the new features.

Enhancements to EarlyStopping functionality:

• Added a new mode parameter to EarlyStopping, allowing users to specify whether to maximize or minimize the score. The logic for improvement now supports both directions. [1] [2] [3]
• Improved handling of min_delta and min_delta_mode to support both absolute and relative changes, with explicit logic for each mode and direction. [1] [2]
• Updated validation in the constructor to check for valid values of mode and min_delta_mode. [1] [2]

Documentation updates:

• Expanded docstrings to clarify the new mode parameter and the behavior of min_delta_mode, including detailed examples for both maximization and minimization. [1] [2]

Testing improvements:

• Added new unit tests to verify correct behavior for minimization mode, including tests for absolute and relative delta, and cumulative delta scenarios.

Other changes:

• Updated the Python version requirement in pyproject.toml to allow Python 3.14.…roved score evaluation

oh okay I would do that, why the builds are failing though, is it because I changes the python version requirements in project.toml?

It's due to unmaintained visdom package, #3526
