Summary

• replace pyright with ty in the dev dependency set, lockfile, and lint task
• remove the old pyright configuration and let Ruff enforce unused-code checks again
• keep VS Code recommendations aligned with the remaining Pylance inlay hint settings while removing the pyright-style strict type-check setting
• fix the color type alias so ty passes with --error-on-warning

Validation

• python -m uv run ruff check .
• python -m uv run pytest --reruns 3 --reruns-delay 1

.vscode/settings.json still contains Pylance-specific analysis/inlay-hint settings, and the PR description mentions keeping VS Code recommendations aligned with those settings, but this change removes the ms-python.vscode-pylance extension recommendation. Consider re-adding Pylance to the recommendations list (alongside astral-sh.ty), or remove the Pylance-specific settings if Pylance is no longer intended to be used.
