Fixed LOTS of bugs • Should flow much easier now. Universal File Converter • HEIC → JPEG, RTF → TXT, plus pluggable strategy pattern for future types—just upload & go. True Tab Multitasking • Brand-new Tab enum drives the entire nav stack—jump between chats & vector stores instantly. Instant Vector-Store Actions • Optimistic deletes & uploads with real-time file counts; rollback safety net if the API balks. Turbo-Loading & Empty States • Dynamic progress messages, glassmorphism spinner, and a guided “no assistants yet?” screen. Auto-Refresh Everywhere • Observer & NotificationCenter overhaul keeps chats, assistants, and vector stores in sync—no pull-to-refresh required. Background-Safe Fetch Queue • New serial queue prevents race conditions when hammering the OpenAI API. Codebase TLC • Cleaner project file, tighter Combine pipelines, smaller debounce windows, and 800 net LOC of fresh Swift. Reasoning-Effort Picker Fix • Removed redundant “Default (medium)” option—caption now clarifies Medium is default. Massive README Overhaul (devs: see GitHub) — 15 commits • +1 200 / −460 LOC • 4 Features • 5 Improvements • 1 Fix
