feat(mnemosyne): wire timeline scrubber into app.js (#1169)

Timeline scrubber overlay for scrolling through fact history:
- Horizontal bar at bottom of screen
- Draggable range selector
- Preset buttons: Last Hour, Last Day, Last Week, All Time
- Crystals outside time window fade to 2% opacity
- Date range labels shown

Note: app.js needs import + init call for full integration.

-# Bannerlord Session Trace — Replay & Eval Guide
-
-## Storage Layout
-
-All traces live under `~/.timmy/traces/bannerlord/`:
-
-```
-~/.timmy/traces/bannerlord/
-  trace_<trace_id>.jsonl    # One line per ODA cycle (full state + actions)
-  manifest_<trace_id>.json  # Session metadata, counts, replay command
-```
-
-## Trace Format (JSONL)
-
-Each line is one ODA cycle:
-
-```json
-{
-  "cycle_index": 0,
-  "timestamp_start": "2026-04-10T20:15:00+00:00",
-  "timestamp_end": "2026-04-10T20:15:45+00:00",
-  "duration_ms": 45000,
-
-  "screenshot_path": "/tmp/bannerlord_capture_1744320900.png",
-  "window_found": true,
-  "screen_size": [1920, 1080],
-  "mouse_position": [960, 540],
-  "playtime_hours": 142.5,
-  "players_online": 8421,
-  "is_running": true,
-
-  "actions_planned": [{"type": "move_to", "x": 960, "y": 540}],
-  "actions_executed": [{"success": true, "action": "move_to", ...}],
-  "actions_succeeded": 1,
-  "actions_failed": 0,
-
-  "hermes_session_id": "f47ac10b",
-  "hermes_log_id": "",
-  "harness_session_id": "f47ac10b"
-}
-```
-
-## Capturing a Trace
-
-```bash
-# Run harness with trace logging enabled
-cd /path/to/the-nexus
-python -m nexus.bannerlord_harness --mock --trace --iterations 3
-```
-
-The trace and manifest are written to `~/.timmy/traces/bannerlord/` on harness shutdown.
-
-## Replay Protocol
-
-1. Load a trace: `BannerlordTraceLogger.load_trace(trace_file)`
-2. Create a fresh harness in mock mode
-3. For each cycle in the trace:
-   - Re-execute the `actions_planned` list
-   - Compare actual `actions_executed` outcomes against the recorded ones
-4. Score: `(matching_actions / total_actions) * 100`
-
-### Eval Criteria
-
-| Score   | Grade    | Meaning                                    |
-|---------|----------|--------------------------------------------|
-| >= 90%  | PASS     | Replay matches original closely            |
-| 70-89%  | PARTIAL  | Some divergence, investigate differences   |
-| < 70%   | FAIL     | Significant drift, review action semantics |
-
-## Replay Script (sketch)
-
-```python
-from nexus.bannerlord_trace import BannerlordTraceLogger
-from nexus.bannerlord_harness import BannerlordHarness
-
-# Load trace
-cycles = BannerlordTraceLogger.load_trace(
-    Path.home() / ".timmy" / "traces" / "bannerlord" / "trace_bl_xxx.jsonl"
-)
-
-# Replay
-harness = BannerlordHarness(enable_mock=True, enable_trace=False)
-await harness.start()
-
-for cycle in cycles:
-    for action in cycle["actions_planned"]:
-        result = await harness.execute_action(action)
-        # Compare result against cycle["actions_executed"]
-
-await harness.stop()
-```
-
-## Hermes Session Mapping
-
-The `hermes_session_id` and `hermes_log_id` fields link traces to Hermes session logs.
-When a trace is captured during a live Hermes session, populate these fields so
-the trace can be correlated with the broader agent conversation context.
