Epic: Ava Tool Trace Viewer Mini-App

Add a Telegram mini-app that allows users to view full tool call traces from Ava's responses. When Ava uses tools, she can include a clickable link that opens an expandable view of the tool inputs/outputs.

Problem

Currently when Ava (Telegram bot) uses tools like python_exec, run_bash, read_file, etc., the user only sees a brief summary in the chat. There's no way to see the full tool input/output, which makes debugging and understanding Ava's actions difficult.

Solution

Store tool traces in SQLite and serve them via a lightweight web server. Include a 'view trace' link in Ava's messages that opens a mobile-friendly HTML page showing the full trace.

Architecture Overview

1. Storage: SQLite table in existing $AVA_DATA_ROOT/ava.db 2. Web Server: New Warp server in Omni/Ava/Web.hs (port 8079) 3. UI: Single HTML file with embedded CSS/JS, no build step 4. Integration: Store trace on tool exec, include link in response
