Review round: the footer hint is drawn only at rest, so nothing arms the idle check while the Run this command list is up. The stock.ts comment, wiki, changeset and test now say a pending approval shows as working until answered, and the test pins busy during the confirmation. Adds the antigravity copy of the reattached-pane settle test, and updates the promptGlyph comment and the fixture header.
agy animates an 8-dot braille spinner (⣯ ⡿ ⣻ ⣾ ⣷ ⣟ ⢿ ⣽) with a label one row above
the composer, none of which is in SPINNER_PATTERN, and the entry declared no
workDetect, so no frame ever marked a tab working.
Declare the working line from the live pane and the footer hint `? for shortcuts`
as the idle-arming mark. The composer's `>` cannot be the glyph: the echoed
prompt starts with it too. Tests use verbatim captures from agy 1.3.3.
