fix(app): Work Column maximize does not fill the full window width (#1434) #1609
Description
Important
Problem — When the Chat is collapsed via the maximize toggle or Cmd+Shift+M, the Work Column does not expand to fill the entire available width. It stops short, leaving dead space.
Approach — Debug and fix: trace from workColumnWidth memo through the flex layout to identify where the cap, padding, or flex constraint prevents full expansion. The memo sets sessionPanelAvailable() as the width when collapsed, but the container may have gap, padding, or a minimum flex-basis on the Chat div that reserves space even when hidden.
Scope — In: the Work Column fills 100% of the available row when Chat is collapsed. Out: animation, button placement, drag feel.
Acceptance Criteria
- When Chat is collapsed (via button, Cmd+Shift+M, or drag), the Work Column fills the entire flex row with no dead space on the left
- The
gap-1.5on the flex row does not reserve space for the hidden Chat panel - Works at any window width

Blocked on PR #1548 (Chat collapse and flexible split), which is deferred until after 0.4.0. This builds on it, so it's marked
hitlto keep the night runner off it until #1548 lands. (0.4.0 cleanup)
