Greptile Overview

Greptile Summary

This PR adds proper open source licensing to the OpenChat project by introducing the GNU Affero General Public License v3 (AGPLv3). The changes include adding a complete LICENSE file with the AGPLv3 text and updating the README.md to include a license section with copyright attribution. The AGPLv3 is particularly well-suited for OpenChat since it's a networked application with both web and server components - this license ensures that any modifications deployed as services must make source code available to users. The copyright is attributed to "OpenChat" for 2025, and the README properly references the LICENSE file for full terms. This is purely a legal/documentation change with no functional impact on the codebase.
