frontend: trim narrated-history comments in packages/agent, packages/swarm-ui

Continues #3901. Same pattern as tabs.js/swarm.js: cut 'used to be
X, now Y'/'moved to'/'no longer' change-history narration down to
the current design fact, keep every load-bearing rationale intact
(the ResizeObserver feedback-loop note in Header.tsx, the Dropdown-
vs-real-<a> semantics in MetaNav.tsx, etc.).
