[rolandwalker]

Description

The tabulate library was updated on PyPi (for the first time in a while), and that update contained a compatibility issue solved in the latest version of cli_helpers.

1. Potential version-floor mismatch for the stated bugfix
   At pyproject.toml:19, cli_helpers[styles] ~= 2.11.0 allows any 2.11.x, including 2.11.0. If the tabulate compatibility fix landed in a later patch (for example 2.11.1+), this range does not guarantee it.
   Action: set the minimum to the exact known-good patched release (for example >=2.11.1,<2.12) and reference that upstream version in the PR description/changelog.

2. Missing regression test for the tabulate compatibility path
   This PR relies entirely on a dependency bump, but there’s no test that would fail with the broken tabulate/cli_helpers combo and pass with the fixed one. That makes future regressions likely if dependency ranges change again.
   Action: add a focused test that exercises table rendering/formatting through the cli_helpers integration path and asserts the previously broken behavior.
