Module cache 

Cache management and memory-mapped I/O

The cache module handles the .reflex/ directory structure:

• meta.db: Metadata, file hashes, and configuration (SQLite)
• tokens.bin: Compressed lexical tokens (binary)
• content.bin: Memory-mapped file contents (binary)
• trigrams.bin: Trigram inverted index (per-file varint blocks, V4 format)
• config.toml: Index settings (TOML text)
