Logger dependency fix

Replaced external Logger import with console fallback in json-parser.ts:

// Before: import { Logger } from './logger';
// After:
const logger = {
  info: (...args: any[]) => console.info('[json-parser]', ...args),
  warn: (...args: any[]) => console.warn('[json-parser]', ...args),
  error: (...args: any[]) => console.error('[json-parser]', ...args),
  debug: (...args: any[]) => console.debug('[json-parser]', ...args),
};

Unused imports removed

• gamification-service.test.ts: DEFAULT_SCORING_CONFIG, ScoringResult
• base-tool.test.ts: ToolExecutionResult
• mcp-logging.test.ts: MCP_SANITIZATION_CONFIG
• sanitization.test.ts: DEFAULT_CONFIG
• mock-data-generator.test.ts: LeaderboardEntry
• check-comments.ts: path

Unused variables fixed

• redis-utils.ts: nextCursor → [, batch] destructuring
• sanitization.ts: [type, pattern] → pattern via Object.values()
• check-doc-links.ts: [, text, link] → [, , link] destructuring

Redis existsPattern bug fix

• Fixed existsPattern method in redis-utils.ts to properly iterate through all SCAN results
• Method now uses a do...while loop to continue scanning until cursor returns '0'
• Returns true immediately when matching keys are found, false only after exhausting the entire keyspace

Review completed. This PR addresses linting issues by removing unused imports and variables, fixing date formats in documentation, and cleaning up duplicate directories. One issue was identified in the redis-utils.ts file.

• Fix existsPattern method in redis-utils.ts to properly iterate through all matching keys instead of only checking the first batch

The existsPattern method only performs a single SCAN operation and doesn't iterate through all matching keys. If the pattern matches keys beyond the first batch (COUNT=10), this will incorrectly return false even when matching keys exist. The method should either loop until cursor returns '0' or be documented as only checking the first batch.

Fixed in 0486f12. The existsPattern method now uses a do...while loop to iterate through all SCAN results until cursor returns '0'. Returns true immediately when any matching keys are found, and false only after exhausting the entire keyspace.

@clduab11, I've completed a comprehensive review of all changes in PR #11. Here's the final analysis:

✅ All PR Objectives Successfully Implemented

🔧 Critical Bug Fixes

1. Redis existsPattern Bug - FIXED
The critical SCAN bug you identified has been properly resolved:

// Before: Single scan operation (incorrect)
const [nextCursor, batch] = await this.redis.scan(cursor, 'MATCH', pattern, 'COUNT', 10);
return batch.length > 0;

// After: Complete iteration with do...while loop (correct)
do {
  const [nextCursor, batch] = await this.redis.scan(cursor, 'MATCH', pattern, 'COUNT', 100);
  if (batch.length > 0) {
    return true;
  }
  cursor = nextCursor;
} while (cursor !== '0');
return false;

• ✅ Now iterates through all matching keys until cursor returns '0'
• ✅ Returns true immediately on first match (performance optimization)
• ✅ Increased COUNT from 10 to 100 for better batch efficiency
