Usage: ci.ps1 [options]

Runs the local sequence for the same check IDs enforced by GitHub CI.
Requires uv on PATH when running ruff, ty, or pytest checks.
Local ruff checks repair formatting and autofixable lint before later checks.

Checks (in order):
  suppressions   Ban type ignores and legacy future annotations
  ruff-format    uv run ruff format
  ruff-check     uv run ruff check --fix
  ty             uv run ty check
  pytest         uv run pytest -v --tb=short

Options:
  -Only ID              Run only the given check (repeatable)
  -Skip ID              Skip the given check (repeatable)
  -DryRun               Print commands without running them.
  -Help                 Show this help text.
