kami f2be46a743 refactor(tui-go): move session dates to the R overlay; drop dead idle panels
The launcher removed the idle session list, so the per-row date moves to the R
resume overlay — now the sole session list. sessionListRow shows an absolute
local date (absDateISO → shortDateTime) alongside the relative age:
"Jun 22 14:30 · 5m ago", with the year shown for older-than-this-year rows.

Delete the now-unused idle-panel renderers (sessionRows / welcomeRows /
workflowRows) and renderMainNarrow's dead idle branch (renderLauncher owns idle,
narrow included). Add a "resume" preview kind to screenshot the R overlay.
