Render Manifest Rows With Compact State Grammar

[csfh]

Parent

#178

What to build

Update Manifest rows to use compact RuntimeStatus codes, quieter healthy metadata, and the selected rail marker. Rows should prioritize Managed Process identity while preserving important retry, exit, and restart signals.

Acceptance criteria

• Rows render Run, Rty, Err, Blk, Str, Stp, Off, Pau, and Unk from runtimeStatus.\n- [ ] Selected Manifest row uses ┃ instead of > and unselected rows reserve the same rail width.\n- [ ] Process names use normal foreground while Process State code and selected rail carry state color.\n- [ ] Rty rows show right-aligned countdown metadata.\n- [ ] Err rows show Ext n only for non-zero exit codes.\n- [ ] Run rows show Rst n only when restart count is non-zero.\n- [ ] No-signal metadata such as Rst 0, Ext 0, and absent exits is hidden.\n- [ ] Narrow row widths hide metadata before state code or process name.
