patches: add affinescript-dom-licensing.patch (MPL-2.0 + CC-BY-SA-4.0)

Durable copy of the affinescript-dom licensing correction (unpushable to the
out-of-scope hyperpolymath/affinescript). Standalone, manually-applied: corrects
the DOM connector from a mislabelled AGPL header to MPL-2.0 (code) +
CC-BY-SA-4.0 (docs) and evidences it in LICENSES/, the Mustfile, CODEOWNERS,
MAINTAINERS, and GOVERNANCE.

-Patches applied to a fresh `hyperpolymath/affinescript` checkout by
-`scripts/install-affinescript-toolchain.sh` before building the compiler, to
-support the ReScript -> AffineScript migration. Each is a stop-gap pending
-upstream; drop it from the install script once upstreamed.
+Patches against a fresh `hyperpolymath/affinescript` checkout, produced during
+the ReScript -> AffineScript migration when `affinescript` was outside the
+session's repo scope (so they could not be pushed upstream directly).
+
+* `affinescript-module-struct-fields.patch` is *applied automatically* by
+  `scripts/install-affinescript-toolchain.sh` before building the compiler
+  (the migration needs it to build).
+* `affinescript-dom-licensing.patch` is a *standalone, manually-applied* patch
+  (repo licensing metadata — not needed to build). Apply it to an `affinescript`
+  checkout you can push, then open a PR upstream.
+
+Each is a stop-gap pending upstream; drop it once upstreamed.
