SSRF test regression (primary blocker) Failing tests in a2a_proxy_test.go get `{"error":"workspace URL is not publicly routable"}` because httptest.NewServer produces loopback IPs (127.0.0.1:N) that isSafeURL blocks. Fix: make isSafeURL overridable via package-level vars: - ssrf.go: safeURLChecker var + isSafeURLDefault function. isSafeURL() is now a thin wrapper — production behavior unchanged. - ssrf_test.go: SetSSRFPermissive(t) helper for tests. Uses t.Cleanup to restore production checker so tests don't leak state. - a2a_proxy_test.go: SetSSRFPermissive(t) added to 31 tests that use httptest.Server URLs. ### 2. Orphaned skipped tests (workspace_provision_test.go) Deleted 3 t.Skip tests + their dead-code helpers (captureBroadcaster, errInternalDB, errInternalOS, containsUnsafeString, mockEnvMutator, mockPluginsSources) — they block compile via type mismatch with WorkspaceHandler.broadcaster. The helpers were only referenced by the skipped tests and are no longer needed. Note: pre-existing dead code in budget.go (patchBudgetRequest type) and workspace_crud.go (sensitiveUpdateFields var) is preserved — both have legitimate comments explaining why they're kept (type used in ShouldBindJSON body parsing; var documents audit risk classification).
