The source headers, LICENSE files, and license metadata had drifted apart. Align the entire project to MIT: - Convert every source-file header to the MIT text across all comment styles (Go, TS, TSX, JS, MJS, SQL, CSS, GraphQL, shell), including SPDX-License-Identifier tags - Set the root and cookie-banner LICENSE files to the MIT text with a "MIT License" title line - Switch the package.json license fields, Docker image label, and cookie-banner README to MIT - Update docs and the genmodels header generator accordingly - Normalize copyright lines to a single format (Copyright (c) <year(s)> Probo Inc <hello@probo.com>.): unify the hello@getprobo.com and hello@probo.inc emails to hello@probo.com and the comma-separated years to a hyphenated range Genuine third-party references are intentionally left untouched: the Lucide icon attributions (Lucide is ISC) and the trivy dependency license allowlist.
