NumberFree V6 — Round 3 (Bug Fixes + Round 2 Features)

Bug Fixes in this release

Fix 1 — Delete chat still reappears on refresh

Root cause: The $nin query used ObjectId comparison but deletedChats stores strings. Fix: conversationController.js now casts stored IDs to ObjectId before the query.

Fix 2 — When deleted user messages you, old messages show but chat missing from list

Root cause: When a newMessage socket event arrived for a conversation not in the local state (because user had deleted it), it was silently ignored. Fix: Home.jsx socket handler now detects when the conversation is missing from local state and re-fetches all conversations from the server to restore it.

Fix 3 — Mobile can’t delete chat (long press not working reliably)

Root cause: Previous fix used onTouchMove to cancel timer, but it fired too aggressively and cancelled the timer even for tiny finger wobbles. Fix: Now tracks start position and only cancels if finger moves MORE than 8px — so accidental micro-movements don’t cancel the long press.
