Go 1.21+ rejects 'replace X => Y vN' when Y's go.mod declares a module
path other than Y. The prior v1.17.8 kept 'module github.com/expr-lang/expr'
while being hosted+required at github.com/hanzoai/expr, so consumers on
Go 1.26 fail with:
module declares its path as: github.com/expr-lang/expr
but was required as: github.com/hanzoai/expr
Rehome the declared module path to github.com/hanzoai/expr and repath all
internal imports to match. Consumers keep 'require github.com/expr-lang/expr'
and 'replace github.com/expr-lang/expr => github.com/hanzoai/expr vX' — the
standard renaming-fork pattern that Go's replace path-check accepts.
