<issue_title>Test coverage for narrativeMemory.js (42.42% → 100%)</issue_title>
<issue_description>## Overview

The narrativeMemory.js manages long-term narrative memory including hourly summaries, daily summaries, timeline lore, and storyline tracking. With 42.42% coverage, significant narrative memory functionality is untested.

Current Coverage

• Statements: 42.42%
• Branches: 52.19%
• Functions: 27.27%
• Lines: 42.42%
• Target: 100% coverage

Uncovered Areas

Major untested sections:

• Memory initialization and loading
• Hourly narrative generation
• Daily narrative generation
• Timeline lore management
• Storyline tracking
• Memory persistence
• Historical data retrieval
• Memory cleanup and archival

Key Functionality to Test

1. Memory Initialization

• Loading historical narratives
• Initializing storage structures
• Configuration handling
• Migration from old formats

2. Hourly Narratives

• Generating hourly summaries
• Topic aggregation
• Sample selection
• Diversity metrics
• Sliding window updates

3. Daily Narratives

• Generating daily summaries
• Aggregating hourly data
• Long-term pattern identification
• Narrative coherence
• Summary formatting

4. Timeline Lore

• Creating lore entries
• Updating lore context
• Lore retrieval
• Lore filtering
• Lore expiration

5. Storyline Tracking

• Tracking ongoing storylines
• Storyline progression
• Storyline completion
• Cross-referencing events

Testing Strategy

describe('NarrativeMemory', () => {
  describe('Initialization', () => {
    test('initializes with historical data');
    test('handles missing data gracefully');
    test('migrates old formats');
    test('sets up storage structures');
  });

  describe('Hourly Narratives', () => {
    test('generates hourly summaries');
    test('aggregates topics correctly');
    test('selects representative samples');
    test('calculates diversity metrics');
    test('updates sliding window');
  });

  describe('Daily Narratives', () => {
    test('generates daily summaries');
    test('aggregates hourly narratives');
    test('identifies long-term patterns');
    test('maintains narrative coherence');
    test('formats summaries properly');
  });

  describe('Timeline Lore', () => {
    test('creates lore entries');
    test('updates lore context');
    test('retrieves relevant lore');
    test('filters by criteria');
    test('handles lore expiration');
  });

  describe('Storyline Tracking', () => {
    test('tracks ongoing storylines');
    test('updates storyline progress');
    test('marks storylines complete');
    test('cross-references events');
  });

  describe('Memory Persistence', () => {
    test('saves narratives to storage');
    test('loads narratives from storage');
    test('handles storage errors');
    test('manages storage limits');
  });

  describe('Integration', () => {
    test('integrates with context accumulator');
    test('provides data to context provider');
    test('supports evolution tracking');
  });
});

Test Fixtures Needed

• Historical narrative data
• Topic time-series data
• Lore entry examples
• Storyline scenarios
• Configuration variations

Acceptance Criteria

• Initialization fully tested
• Hourly narrative generation verified
• Daily narrative generation covered
• Timeline lore management tested
• Storyline tracking verified
• Memory persistence tested
• Overall coverage 100%
