Security audit: Document all API key locations in repository

[Copilot]

Description

Comprehensive security audit identifying all API key occurrences in the codebase. Scan revealed no exposed secrets—only proper environment variable usage and one documented public development key.

Findings:

• 1 hardcoded key: Allora Network public development key (UP-4151d0cc489a44a7aa5cd7ef) in both Python/TypeScript implementations—documented as public testing key, safe
• 10+ environment variables: All sensitive keys (CDP, OpenAI, Twitter, etc.) properly use process.env/os.getenv
• 14 template files: Empty placeholders only (.env.local, .env-local)
• 200+ blockchain addresses: Public smart contract addresses (expected, not secrets)

Documentation added:

• API_KEY_LOCATIONS.md (8.3 KB) - Complete inventory with file paths, categorized by type
• SECURITY_AUDIT_API_KEYS.md (6.8 KB) - Executive summary, risk assessment, scanning methodology
• API_KEY_QUICK_REFERENCE.md (3.2 KB) - Developer quick reference with env var listing

Security status: ✅ PASSED - No private keys exposed, exemplary practices throughout

Tests

No functional changes—documentation only. Verified:

• Pattern scanning (OpenAI/AWS/Google key formats, credential indicators)
• Configuration file discovery (.env*, .config)
• Git history inspection
• .gitignore validation (.env patterns properly excluded)

Checklist

• Added documentation to all relevant README.md files
• Added a changelog entry
