Greptile Summary

This PR adds proper attribution to the open-source Costa Rican community by including an Agradecimientos (Acknowledgments) section that credits the CRLibre projects that provided valuable reference material. The footer is updated to feature Dojo Coding branding with a link to their website.

Changes:

• Added new Agradecimientos section before the license section
• Credits CRLibre/API_Hacienda as the original PHP-based open-source API for Costa Rican electronic invoicing
• Credits CRLibre/fe-hacienda-cr-misc for shared resources and documentation
• Updated footer from generic "Hecho con orgullo..." to "Construido por Dojo Coding" with link to https://dojocoding.io
• Added tagline "Herramientas open-source para desarrolladores costarricenses 🇨🇷"

The changes are documentation-only and properly acknowledge the community contributions while establishing clear project branding.

Confidence Score: 4/5

• This PR is safe to merge with minimal risk as it only modifies documentation
• Score reflects documentation-only changes with proper attribution and branding. No code changes, no functional impact. Minor improvements would make this a 5/5.
