Per the standing fork rule, a hanzoai fork declares its OWN module path and
is required directly -- never resolved via a `replace` against the upstream
path. Keeping the upstream path meant every import line in every consumer
carried the upstream brand.
module github.com/traefik/yaegi -> module github.com/hanzoai/yaegi
Mechanical and behaviour-neutral: every occurrence is an import path
(package self-imports, cmd/, _test/ fixtures interpreted at test time, and
the guthib.com/<org>/{fromage,cheese,vin} fake vendor trees under
example/pkg, whose directory components were renamed in lockstep with the
import strings that reference them).
GOPATH-mode source-import tests (interp TestFile) resolve the module by its
path under $GOPATH/src, so the required checkout location moves with the
module path -- as README already documents. Verified green at
$GOPATH/src/github.com/hanzoai/yaegi.
LICENSE is untouched: "Copyright 2020 Traefik Labs SAS" is the Apache-2.0
attribution and is a legal obligation, not a brand leak.
Also drops the inherited CONTRIBUTING.md CLA clause, which named an
upstream agreement this fork does not administer.
