- Add Redis-based tracking to prevent start.bas from running repeatedly
when clicking suggestion buttons. start.bas now executes only once per
session with a 24-hour expiration on the tracking key.
- Add generic tool executor (ToolExecutor) for parsing and executing
tool calls from any LLM provider. Works with Claude, OpenAI, and
other providers that use standard tool calling formats.
- Update both start.bas execution paths (WebSocket handler and LLM
message handler) to check Redis before executing.
- Fix suggestion duplication by clearing suggestions from Redis after
fetching them.
- Add rate limiter for LLM API calls.
- Improve error handling and logging throughout.

Replace emoji icons with plain text/ASCII equivalents to prevent
encoding issues and improve console compatibility:
- Replace checkmarks with *
- Replace x marks with x
- Replace status indicators with text [OK], [ERR], etc.
- Remove decorative emojis from info/debug log messages
- Keep functional emojis in user-facing chat/sentiment features
