Sorry, something went wrong.
- Remove unused `slow_scalar_pipeline` test fixture
- Remove `{try-notebook}` directive from run-status docs (no Python cells)
- Document implicit headless tracker creation in `_create_progress_tracker`
The warning fires during `import zarr` → numcodecs → google_crc32c and appears on every pipefunc import when the C extension is not compiled. Suppress it in `map/__init__.py` before importing zarr.

Summary
Suppress the google-crc32c pure-python fallback RuntimeWarning that fires on every pipefunc import when the C extension isn't compiled.
Import chain: pipefunc → map/__init__.py → _zarr.py → zarr → numcodecs → google_crc32c 💥
The fix adds a warnings.filterwarnings call in map/__init__.py right before the zarr import (which is already inside a suppress(ImportError) block).
