Pull request overview

Updates Python developer tooling (Ruff + BasedPyright) and applies small code/test refactors to satisfy new lint/type-check expectations while keeping runtime behavior consistent with the project’s Python 3.11+ baseline.

Changes:

• Bump dev tool versions: basedpyright to >=1.39.9 and ruff to >=0.16.0 (plus lockfile refresh).
• Refactor enums to use enum.StrEnum and apply minor code cleanups prompted by updated linting/type checking.
• Adjust tests and Ruff config to align with updated lint rules (e.g., regex match strings, implicit string concatenation, lazy-import rule ignore in tests).
