style(fmt[markdown]): Format Python blocks in Markdown

why: ruff 0.16.0 formats Python and pycon code blocks inside Markdown by
default, so `ruff format . --check` now fails on docs that were never
run through the formatter. The churn is mechanical - quote style,
argument wrapping, comment spacing, trailing whitespace.

what:
- Reformat the Python blocks in `README.md`
- Reformat the Python blocks in `notes/2025-11-26-command-support.md`
