Make script/test fail on flaky failures and enable -race (closes #32)

script/test ended with `go test ./... || go test -v ./...`, so the
verbose rerun's exit status became the script's. A test that failed
once and passed on the retry produced exit 0, and since the Dockerfile
runs `make test` and CI runs script/cibuild, flaky failures were
invisible repo-wide.

Replace that with the pattern from REPO_POLICIES.md: run
`go test -timeout 30s -race -cover ./...`, and on failure rerun
verbosely and then exit 1, so the rerun is diagnostic only and can
never turn a failed run green. `go vet ./...` still runs first; the
script stays POSIX sh with set -eu, the CGO_ENABLED=1 export, and the
repo-root cd idiom.

Enabling -race surfaced a genuine timing conflict rather than a data
race: no package that ran to completion reported one, but internal/cli
now exceeds the 30s timeout because the 99MB/100MB boundary cases in
secrets_size_test.go are about 10x slower under race instrumentation.
Measured in the CI-equivalent container (script/cibuild, with the
memlock ulimit): 18.7s for the make test layer without -race, versus
internal/cli alone needing roughly 55-60s with it. Neither the flags
nor the tests were weakened to hide this; the conflict is filed as #52
for a decision.

 # Completed Steps

-  `.golangci.yml` (all linters enabled minus the standard disable
+  `go test -timeout 30s -race -cover ./...` and, on failure, reruns
-  list, `lll` 88, tests linted); bumped the `Dockerfile` lint-stage
+  verbosely and then exits non-zero, so a test that fails once and
-  image to the tagged v2.12.2 Debian digest; fixed all ~1550 new
+  passes on the retry can no longer produce a green build (closes #32).
-  findings across `internal/` and `pkg/` (line wrapping, `wsl_v5`
+  Enabling `-race` showed the suite cannot meet the 20-second policy
-  blank lines, sentinel errors for `err113`, `t.Parallel()` where
+  budget: `internal/cli` exceeds the 30-second timeout because the
-  safe, `_test` package conversions, complexity/`dupl` helper
+  99MB/100MB boundary cases in `secrets_size_test.go` run roughly 10x
-  extraction) on branch `golangci-v2.12.2`.
+  slower under race instrumentation. No flags were weakened and no
+  tests skipped; the conflict is tracked in #52 for a decision.
