🧠 EvoMail/COG - Self-Evolving Cognitive Agent for Spam Detection

📝 Description

This PR implements EvoMail/COG - a self-evolving cognitive agent framework for spam detection that mimics human analysts. It uses a Red-Team/Blue-Team adversarial learning approach to continuously adapt to new spam tactics without manual intervention.

🚀 Core Components

1. Red Team (Adversarial Generator)

Generates 9 types of novel evasion tactics to test and strengthen the model:

Attack Type	Description	Example
Character Substitution	Replace chars with lookalikes	claim → cl4im
Synonym Replacement	Replace words with synonyms	free → complimentary
Noise Injection	Insert random characters	free → fr!ee
Sentence Rephrasing	Restructure sentences	Claim now → You can claim today
Homoglyph Attack	Use similar Unicode chars	a → а (Cyrillic)
Padding Attack	Add padding between words	free prize → free . prize
Spacing Attack	Insert extra spaces	free → fr ee
Unicode Smuggling	Use zero-width characters	Hidden text in visible text
Zero-Width Attack	Add invisible characters	free → f‌r‌e‌e

2. Blue Team (Adaptive Detector)

• ✅ Detects model failures
• ✅ Learns from misclassifications
• ✅ Adapts to new attack patterns
• ✅ Tracks adaptation history

3. Memory Module

• ✅ Compresses experiences for future reasoning
• ✅ Stores attack patterns and failures
• ✅ Prevents catastrophic forgetting
• ✅ Extracts relevant experiences for context
• ✅ Importance scoring with decay

4. Cognitive GNN (Graph Neural Network)

• ✅ Builds reasoning graph from memory
• ✅ Traverses connections for insights
• ✅ Synthesizes conclusions from related experiences
• ✅ Enables cognitive reasoning

5. Self-Evolution Scheduler

• ✅ Automatic evolution
• ✅ On-demand manual evolution
• ✅ Status tracking
• ✅ Configurable parameters

Closes #899
