Addresses decodetool#1 by providing a tool to sanitize session logs for sharing. Replaces base64 image data with SHA-256 hashes while preserving structure, reducing file size by ~90% for image-heavy sessions. Usage: node scripts/hash-session-logs.cjs <session-file.jsonl> [output-dir] Features: - SHA-256 hashing of base64 image data - Preserves full JSON structure for debugging - Progress feedback and size reduction reporting - Error handling with line-level recovery
