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
