chore: relicense from GPL-3.0-only to PolyForm-Noncommercial-1.0.0

Switch to source-available licensing that prohibits commercial use while
allowing personal, research, education, nonprofit, and government use.

- Replace GPL-3.0-only with PolyForm-Noncommercial-1.0.0 across all files
- Update SPDX headers in all 38 source files
- Add CLA.md (Indie Open Source Tiny CLA)
- Add CLA Assistant Lite GitHub Action workflow
- Update REUSE.toml, Cargo.toml, README.md, and CLAUDE.md
- Verify REUSE 3.3 compliance (40/40 files)

+
+Fair Use
+
+You may have "fair use" rights for the software under the law. These
+terms do not limit them.
+
+No Other Rights
+
+These terms do not allow you to sublicense or transfer any of your
+licenses to anyone else, or prevent the licensor from granting licenses
+to anyone else. These terms do not imply any other licenses.
+
+Patent Defense
+
+If you make any written claim that the software infringes or contributes
+to infringement of any patent, your patent license for the software

+over, are under the control of, or are under common control with that
+organization. Control means ownership of substantially all the assets of
+an entity, or the power to direct its management and policies by vote,
+contract, or otherwise. Control can be direct or indirect.
+
+Your licenses are all the licenses granted to you for the software under
+these terms.
+
+Use means anything you do with the software requiring one of your
+licenses.
