#9695 chore: Add type checking with ty Pull request opened by edgarrmondragon ## Description ## Related Issues • Closes #XXXX ## Summary by Sourcery Introduce ty-based type checking alongside mypy and perform type-hinting and API cleanups to satisfy the stricter checks. Enhancements: • Add ty as a typing dependency and configure its source and exclusion paths in pyproject.toml. • Run ty in the existing mypy nox session to integrate the new type checker into the local typing workflow. • Rename TaskSetsService.list to list_task_sets and update call sites to use a more descriptive API name. • Tighten type annotations and attribute initialization in plugin environment configuration handling, including config_with_extras and settings updates. • Refine filesystem state store deletion signatures and bundle root resource resolution for clearer, more precise typing semantics. Tests: • Update TaskSetsService tests to use the new list_task_sets API to keep coverage aligned with the refactored service. meltano/meltano
