MAINT Enable ruff rule E (pycodestyle errors)

[romanlutz]

Enable the E rule category covering:

• E402: module import not at top of file (fixed docstring placement, noqa for intentional)
• E501: line too long (wrapped long strings/docstrings to 120 chars)
• E721: type comparison (use 'is' instead of '==')
• E731: lambda assignment (converted to def)

Pull request overview

This maintenance PR enables the ruff E rule category (pycodestyle errors) in the linting configuration to enforce code style consistency across the PyRIT codebase. The changes address four specific error types: E402 (module imports not at top of file), E501 (lines exceeding 120 characters), E721 (type comparisons using == instead of is), and E731 (lambda assignments instead of def statements).

Changes:

• Enabled ruff E rule in pyproject.toml to enforce pycodestyle error checks
• Fixed import placement in 3 files (moved from __future__ import annotations after module docstrings, added noqa comment where intentional)
• Wrapped long strings and docstrings to comply with 120-character line limit in 11 files
• Changed type comparison from == to is in test file
• Converted lambda assignment to proper function definition in discovery module
