docs: add Apache 2.0 LICENSE and link it from the README

Drops the canonical Apache 2.0 text at repo root and adds a License
section to the README with the copyright line. Apache 2.0 picked over
MIT for the patent grant and contributor language, both of which
matter for a security-adjacent tool aiming at corporate-evaluable
adoption. Also tidies the manifest example's GIT_AUTHOR_NAME to use
the project's online handle.
