`depguard` was in the disable list. It is now enabled with one rule, `test-support`: in files that are neither test files nor inside a package whose directory name ends in `test`, the imports named under `deny` are refused. Canonical denies `net/http/httptest`, which serves tests only and is the same in every repository. This replaces `internal/testimportgate` in sneak/homoicon, a package whose only job was to refuse a non-test Go file importing an in-module package whose last path segment ends in `test`. sneak ruled on sneak/homoicon#1029 that the rule moves into linter configuration here. depguard cannot express that rule generically. Its package lists are prefix lists -- its own README says so, and I confirmed it: `*test`, `**test` and `$gomod/**test` each match nothing, while a full import path matches. "In module" is not generic either, since the module path differs per repository. And depguard refuses a rule with no allow or deny list, so this file cannot ship the rule pre-armed and empty for each repository to fill in. The closest expressible rule is the one here. The file half is generic and exact; the package half is a deny list each repository extends with its own test-support packages, by full import path. REPO_POLICIES.md now says that list is the one part of a vendored copy a repository may add to. Tested with golangci-lint v2.12.2 on a scratch module: a production file importing a denied `*test` package fails, and the same import from a `_test.go` file and from inside the `*test` package passes. `make check` here is green.
