Keep 'Not now' as the safe dismiss; demote 'Don't show again' to a muted link

This modal auto-opens unsolicited (first activation of a Linear-linked
worktree with the skill missing), so the reflexive dismiss must be
non-destructive. Removing 'Not now' left the permanent 'Don't show again'
as the only labeled footer button — the reflexive target — which would
nuke a useful prompt forever.

Restore 'Not now' (session snooze) as a quiet ghost — the easy, safe
dismiss, matching Neil's original ask ('not now is fine, just not the
CTA'). Demote 'Don't show again' to a muted text link so permanent
suppression takes intent. Install stays the filled primary.

Restores onSnoozeForSession wiring + notNow i18n key (all locales);
tests exercise the Not now snooze path again.
