Docs: Verify Astrocyte method signatures in tutorial examples

[kluth]

Problem

Tutorial uses Astrocyte methods that need verification against actual implementation.

Affected Files

Documentation: /home/matthias/projects/synapse/docs/getting-started/first-app.md (lines 254-259)
Source Code: /home/matthias/projects/synapse/src/glial/Astrocyte.ts

Issue Details

Severity: MEDIUM
Impact: Tutorial code may fail at runtime with "method not found" errors

Methods Requiring Verification

public getStats() {
  return {
    totalUsers: this.userStore.getKeysByPattern('user:*').length,     // Verify this method exists
    activeSessions: this.sessionStore.getKeysByPattern('session:*').length,  // Verify this method exists
    userStoreStats: this.userStore.getStatistics(),    // Verify this method exists
    sessionStoreStats: this.sessionStore.getStatistics(),  // Verify this method exists
  };
}

Tasks

1. Check if Astrocyte.getKeysByPattern() exists in source code
2. Check if Astrocyte.getStatistics() exists in source code
3. If methods don't exist, find correct method names
4. Update tutorial with correct API calls

Priority

MEDIUM - Code verification needed to ensure tutorial accuracy

• Documentation Fixes Needed: /home/matthias/projects/synapse/DOCUMENTATION_FIXES_NEEDED.md (FIX-6)

User Story

As a developer following the tutorial, I want method calls to match actual implementation, so that my code runs without method-not-found errors.

Acceptance Criteria

• Verify getKeysByPattern() method exists or find alternative
• Verify getStatistics() method exists or find alternative
• Update tutorial code with correct method names
• Test that updated code executes successfully
