Subject: [PATCH] fix(tests): use glob instead of regex in nix-shell test

The NIX_BUILD_TOP test used regex matching with an unquoted path
variable. When the path contains `+` (or other regex operators),
the test fails because `+` is interpreted as a quantifier rather than
a literal character. Glob matching handles these characters correctly.
