fix: add click compatibility layer for CLI alias support

[cofin]

Summary

• Adds a compatibility layer (advanced_alchemy/utils/cli_tools.py) that provides click alias support across all environments
• The aliases parameter in click groups is a rich-click 1.9+ feature that causes TypeError when users have plain click or older rich-click
• Implements AliasedGroup class that mimics rich-click's alias handling for plain click
• Updates all CLI modules to use the new compatibility layer

Problem

Users encounter failures when using the CLI in these scenarios:

Scenario A: Plain click (no rich-click)

TypeError: __init__() got an unexpected keyword argument 'aliases'

Scenario B: Old rich-click (< 1.9.0)

TypeError: __init__() got an unexpected keyword argument 'aliases'

Solution

Created advanced_alchemy/utils/cli_tools.py with:

• AliasedGroup class that implements alias resolution for plain click
• group() and command() wrapper decorators that auto-select the appropriate class
• Detection constants (_RICH_CLICK_AVAILABLE, _RICH_CLICK_ALIASES_SUPPORTED)

Changes

File	Change
advanced_alchemy/utils/cli_tools.py	New compatibility module
tests/unit/test_utils/test_click.py	Unit tests for the module
advanced_alchemy/cli.py	Updated to use compatibility layer
advanced_alchemy/extensions/fastapi/cli.py	Updated to use compatibility layer
advanced_alchemy/extensions/flask/cli.py	Updated to use compatibility layer
advanced_alchemy/extensions/litestar/cli.py	Updated to use compatibility layer

Test plan

• Unit tests for AliasedGroup class
• Tests with mocked plain click (no rich-click)
• Tests with mocked old rich-click (< 1.9.0)
• Tests with new rich-click >= 1.9.0
• Type checking passes (mypy/pyright)
• Linting passes (ruff/pre-commit)
