fix: Remove duplicate atlas-toggle-btn ID (#1336)

## Summary
Fixed duplicate `atlas-toggle-btn` ID in index.html.

## Problem
There were 2 buttons with the same ID `atlas-toggle-btn`:
1. Line 168: Incomplete button with title="World Directory"
2. Line 176: Complete button with title="Portal Atlas"

The first button was incomplete (missing closing tag and content).

## Solution
Removed the duplicate and incomplete button (line 168).
Kept the complete button with title="Portal Atlas".

## Changes
- Removed duplicate `atlas-toggle-btn` button from index.html
- Now only 1 button with this ID exists

## Testing
- Verified no duplicate IDs remain in index.html
- No merge conflict markers found
- File is clean and ready for merge

Issue: #1336

+Bannerlord Session Trace Logger — First-Replayable Training Material
 
-Provides BannerlordTraceLogger for the bannerlord_harness module.
-Real implementation logs game events to structured telemetry.
+Captures one Bannerlord session as a replayable trace:

+  - Actions executed with success/failure

+Storage: ~/.timmy/traces/bannerlord/trace_<session_id>.jsonl

+Each JSONL line is one ODA cycle with full context.
+The manifest bundles metadata for replay/eval.
