feat(native-chat): say terminal sessions kept running, and clear the quality gate

The modal lists stopped chats with no way to tell that CLI agents are fine, and
the true state of the world is counterintuitive: the terminal sessions survived
the restart and the chats did not. One line now says so, next to the heading
where it frames the list rather than as a footnote at the bottom.

Wording follows the app's own vocabulary rather than inventing a term: the
catalog settles on "terminal sessions" (terminalSessionCount, "Terminal sessions
are grouped by workspace", "No terminal sessions yet"), and UpdateCard already
reassures with "Your terminal sessions won't be interrupted during the update" in
the same text-xs text-muted-foreground treatment. "kept running" rather than
"were restored" -- nothing reconnected them, they never stopped, and the line
says nothing about why.

Also clears check:code-quality:changed, which I had not been running -- oxlint
alone covers neither the design-system nor the casting audit, so 18 findings had
accumulated across the branch.

  - design system (4): Button spacing hand-rolled as gap-1/px-2 is just size="xs";
    PopoverContent and DialogTitle own their typography and spacing, so the
    text-xs moved to the popover's own children and the title's icon gap moved to
    a plain wrapper.
  - casting (14): production code loses its assertions outright via Reflect.get,
    the idiom already used in managed-hook-detection-commands and
    worktree-name-retirement. The marker validator reads each field through
    Reflect.get and now checks recordedAt is a number rather than asserting it;
    the store-file parse uses the existing `file` shape instead of a second
    assertion; the runner narrows the admission error's owner with typeof.
    Test fixtures keep their assertions behind the line-specific SAFETY:
    rationale the repo mandates for exactly this case.

One trap worth recording: the audit reports an assertion at the line its
EXPRESSION OPENS, not where `as` appears, so a disable-next-line above the
closing brace of a multi-line literal is inert and silently changes nothing.

Guards unchanged; ablation re-proved 14/14 at this head.
