v0.9.0 - The "Social & Stability" Update

This major release introduces the highly anticipated Group Chat system, bringing multiplayer dynamics to TavernRev, alongside massive architectural improvements and performance optimizations.

[Group Chats]

• Multi-Character Support: Create rooms with multiple characters and chat with them simultaneously.
• Advanced Routing Engine: Three strategies to determine the next speaker:
  • Natural Order: Smart mention parsing (whole words/partial names) combined with character-specific Talkativeness weights.
  • List (Round Robin): Strict sequential turn-taking for structured roleplay.
  • Manual Selection: Choose the next speaker explicitly via a dedicated UI modal.
• Group Management:
  • Scenario Override: Define a global context/setting for the entire group.
  • Member Controls: Easily add/remove characters or "Mute" them to prevent auto-responses.
  • Custom Avatars: Upload unique icons for your groups.
  • Self-Response Control: Prevent characters from talking to themselves with the "Allow Self-Responses" toggle.

[Cloud Synchronization]

• Full Group Sync: Your groups, members, and settings are now fully synchronized across devices via Google Drive and Dropbox.
• Resilient Delta Sync: Individual file failures no longer abort the entire sync process.
• Safe Transfers: Implemented SQL transactions for chat imports to prevent data loss during network interruptions.

[Character & Prompt Engine]

• Message Examples (Few-Shot): Added full support for the mes_example block with intelligent <START> tag and role prefix parsing. This dramatically improves the AI's ability to mirror character style.
• Talkativeness Slider: Fine-tune how often each bot participates in group conversations directly from the Character Editor.
• Macro Fixes: All STScript macros ({{getvar}}, {{random}}, etc.) are now faster and more reliable.

[Performance & Security]

• CPU Optimization: Macro and template parsing is now handled by a global, thread-safe registry, reducing generation-time overhead by up to 90%.
• Network Pooling: Implemented persistent HTTP connection pooling for faster API response times.
• Data Integrity: Switched to strict serde_json serialization across the database layer, replacing fragile manual string escaping.
• Stability: Fixed numerous potential panics (unwraps) and added robust error handling for React promise rejections.

[UI/UX Fixes]

• Console Overhaul: The System Console now features categories (AI Prompt, DB, System, Errors) and a manual "Fetch Latest Prompt" button.
• Better Text Editing: Fixed the "jumping" bug in the auto-resizing text area when editing large messages.
• Smart Impersonate: The "Impersonate me" feature now takes your current typed draft into account and "improves" it directly in the input box.
• Minecraft-style Splashes: Updated splash screen messages to celebrate the v0.9.0 milestone!
