Switches the project from AGPL to a source-available license that
restricts commercial use — selling oAI or any part of it, standalone
or bundled into another product/service, now requires a separate
commercial license from the copyright holder. Noncommercial use,
study, modification, and sharing remain fully permitted.
Updates: LICENSE (canonical PolyForm Noncommercial 1.0.0 text +
commercial licensing contact note), SPDX headers and file-header
boilerplate across all Swift source files, the in-app About dialog's
license link (+ its localization catalog entry), README.md and
DEVELOPMENT.md license sections.
