Laranon: Reversible PII anonymization for Laravel LLM apps

Laranon is a Composer package that detects and replaces PII with stable placeholders before sending data to LLMs, then restores real values in responses. It validates checksums for IDs like DNI, IBAN, and credit cards, and tokenizes names per word to avoid false positives. The token map stays in memory per request, with an optional database vault for queued jobs.
