Summary

Follow-up polish on the redesigned Sessions page: replace the status pills with a plain dot + label treatment and drop the Runtime column from the roster, moving agent runtime (and run duration) into the row details drawer.

Problem to solve

Feedback on the initial redesign (#102517, landed in #102523):

• The status pills (bordered, filled, fully rounded) add chrome the roster does not need; with kind badges and label chips beside them, rows read as a wall of pills.
• The Runtime column (agent runtime id such as pi/codex) is rarely consulted while scanning the roster; it costs ~130px per row that the key, status, and tokens columns could use, and per-session detail already has a home in the row drawer.

Proposed solution

• Status renders as a colored dot plus a plain text label: green pulsing dot for Live, neutral label with a green dot for Done, muted for Idle/Unknown, red for Failed. No background, border, or pill radius. The same treatment applies in the row drawer hero.
• Remove the Runtime column; the drawer's detail grid gains "Runtime" (agent runtime label) and "Run duration" (previously the drawer's only runtime stat). Runtime remains searchable from the filter box.
• Reflow the responsive breakpoints for the 7-column roster and reclaim the actions column width (the row menu from feat: session context menu (kebab + right-click) on the Sessions page #102564 already collapsed the action buttons).

Alternatives considered

• Restyling the pills to be squarer/quieter: still competes with the kind badge; a typographic status is calmer and matches status treatment in the overview tiles.
• Keeping Runtime but narrower: the value is low-frequency diagnostic info; the drawer is the documented place for that tier of detail.

Impact

• Affected: Control UI Sessions page users.
• Severity: cosmetic/ergonomic polish.
• Frequency: every Sessions page visit.
• Consequence: calmer rows, more room for identity/status/tokens, no information loss (runtime moves to the drawer).
