Note

Low Risk
Help text formatting and tests only; no auth, data, or runtime behavior changes.

Overview
The entire labs help table no longer uses a fixed 16-character invocation column. renderExperimentalCommands now pads each row to the longest invocation in the list, and padRight measures width with utf8.RuneCountInString instead of byte len, so summaries line up correctly for multi-byte text.

New tests assert that summary columns align for the real registry and that the column widens when a longer invocation is added.

Pull request overview

This pull request updates the entire labs help-table rendering so command summaries align without relying on a fixed-width invocation column, and adjusts padding to be UTF-8 rune-aware.

Changes:

• Compute the invocation column width dynamically based on the longest invocation in the list.
• Update right-padding logic to measure string length by rune count instead of byte length.
• Add tests asserting summary-column alignment and that the column widens when a longer invocation is present.
