ci: cache Go builds per job and run envtest alongside unit - #22

Conversation
- setup-devtools keys the Go cache by job. With one shared key the first job to finish saved it; on PR #21 that was Security, which compiles nothing, so every job restored a 221-byte cache and never saved again. Also caches golangci-lint's own cache. - CI also runs on push to main (E2E skipped) so main holds warm caches: a PR can only restore caches from its own ref or main. - envtest no longer waits for unit; e2e waits for unit only.
