Relicense to GPL-3.0-only and add SPDX license headers (#346)

lippserd · web-flow · commit c55a4b2f1d14 · 2026-03-11T21:50:15.000+01:00
Relicense this module to `GPL-3.0-only`. Replace the old license file
with `LICENSE.md` and update documentation references accordingly.
Add `GPL-3.0-or-later` SPDX license headers to source files, allowing
relicensing under future GPL versions. This ensures compatibility with
third-party dependencies (e.g. `Apache-2.0`) incompatible with
`GPL-2.0-only`.
