Subject: [PATCH] Refactor: split overgrown files into focused modules
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Split client.ts (1036 lines) into 11 domain modules under lib/nostr/ —
core, notes, social, articles, engagement, dms, bookmarks, muting,
search, relays, trending. Barrel index.ts re-exports all; zero consumer
import changes.

Extract ProfileView sub-components (ImageField, Nip05Field,
EditProfileForm, ProfileMediaGallery), NoteContent renderers
(TextSegments, MediaCards), and NoteCard actions (NoteActions,
InlineReplyBox). All component files now ≤270 lines, all lib files ≤300.
