chore(deps-dev)(deps-dev): bump marimo from 0.21.1 to 0.22.4 in the python-dependencies group

[dependabot]

Bumps the python-dependencies group with 1 update: marimo.

Updates marimo from 0.21.1 to 0.22.4

Release notes

Sourced from marimo's releases.

0.22.0

What's Changed

This release brings a unified data table explorer, reliability improvements to the programmatic notebook API that power the new marimo-pair agent skill, smarter numeric formatting in tables, faster mo.persistent_cache, and a contextual tips system in the CLI.

⭐ Highlights

Combined row viewer and column explorer

The row viewer and column explorer panels are now unified into a single tabbed "Table Explorer" pane. A single toolbar button opens and closes the panel; Rows and Columns tabs live inside it, and your selected tab persists across open/close.

Pair programming with marimo-pair

The experimental _code API receives reliability fixes in this release, enabling the new marimo-pair agent skill for pair programming in marimo notebooks.

🚨 Breaking changes

mo.image no longer normalizes uint8 values (#8889)

Previously, mo.image() normalized all numeric arrays (including uint8) to the [0, 1] float range. Now, uint8 arrays are always rendered with values in [0, 255] without normalization. Two new parameters — vmin and vmax — let you set explicit value bounds for under- or over-saturated displays. If you relied on the old uint8 normalization, pass vmin=0, vmax=1 explicitly.

__marimo__ location now follows sys.pycache_prefix (#8797)

The __marimo__ directory now respects sys.pycache_prefix, consistent with Python's own __pycache__ placement. This also fixes cache placement for notebooks in nested directories. Existing caches will not be migrated — they can be safely deleted.

Cache version bump (#8793)

The cache format version has been bumped, invalidating existing caches.
