Fix Ruff lint violations

[timkpaine]

Description

Update Python sources and tests for current Ruff checks without changing lint configuration. Modernize annotations, simplify flagged constructs, remove duplicate parameter cases, and preserve compatibility-sensitive exception behavior with targeted inline suppressions.

Type of Change

• Bug fix
• New feature
• Documentation update
• Refactor / code cleanup
• CI / build configuration
• Other (describe below)

Checklist

• Linting passes (make lint)
• Tests pass (make test)
• New tests added for new functionality
• Documentation updated (if applicable)
• Changelog / version bump (if applicable)

Focused verification passed 1,296 tests. One additional config-loader test and completion tests fail locally because unrelated installed entry-point plugins add 33 unexpected config groups; this is environment contamination rather than a change introduced here.
