V1.6 - Improve app and add new functions

What's new

Codex local log support

Tether now reads local Codex events and builds trace nodes directly from your logs. No proxy setup required — just point Tether at your Codex log directory and get full trace visibility out of the box.

Execution graph

The graph has been expanded beyond LLM call trees. You now see the full picture of what your agent actually did:

• Requests and responses
• Modified files with diffs and line counts
• Shell, test, and git events
• Failed states with recovery actions

This makes it significantly easier to understand why an agent run went wrong and what it attempted to fix.

Graph navigation

• Clicking a node in the sidebar now moves the camera to that node in the graph
• Keyboard shortcuts reviewed and updated
• Replay and compare actions for local Codex log nodes now work correctly
