Enable depguard so a non-test file cannot import test support (#59)
`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.
