WebSocket System Rework & General Improvements

• WebSocket architecture rewrite — New WsHandler base class, WsManager for connection tracking, event routing, and buffering; reduces WebSocket init from ~170 lines to ~10. Frontend adapter updated with exponential backoff, envelope validation, 50 MB cap, and improved handler registration.
• WebSocket security fix — dispatch_to_all_sids snapshot now taken inside the lock to prevent security check bypass during concurrent disconnects.
• WebSocket memory leak fixes — Resolved SID retention after disconnection and cleaned up unreferenced broadcast tasks.
• API/WebSocket caching — WebSocket and API caching parameters are now enabled.
• a0_small prompt set — New compact prompt set for small models, reducing initial token usage from ~10k to ~2.5k tokens. Includes stricter tool-call guardrails, canonical JSON examples, exact tool-name matching, and memory usage hints.
• Fix: non-ASCII filename uploads — Resolved a 500 error when uploading images with non-ASCII filenames via /api/image_get; adds graceful fallback for path handling in both development and Docker environments.
• Fix: agents self-correct tool call format — Agents now attempt to fix their own malformed tool calls instead of immediately erroring.
• UI: chat navigation buttons — Repositioned as a floating overlay in the bottom-right of the chat area.
• Log sanitization — Printed output and HTML logs are now sanitized to handle invalid Unicode (including lone surrogates); log files opened with utf-8 and errors='replace'.
• Plugin installer — Centralized popularity checking with a configurable POPULAR_PLUGIN_MIN_STARS threshold.
• Onboarding plugin — Added generated thumbnail.
