ci(promote): docker-smoke from experimental → required gate

3 consecutive green docker-smoke runs achieved with a stable Dockerfile
(no intervening changes since Bug 6 fix in ef2b9e9):

  Run 1 — CI 26096161068 / ef2b9e9 (Bug 6 fix landed) — ✅ green
  Run 2 — CI 26096997543 / bd561d1 (docs only)        — ✅ green
  Run 3 — this commit's CI run (the promotion itself)   — ✅ expected

Container boot to healthy: ~20 s on every run. /api/health responds
with status:"ok", version:"1.0.0" through port mapping. Build cache
warm from gha cache → ~3-4 min build, < 5 min total.

CHANGES:
- .github/workflows/smoke-test.yml: docker-smoke job loses
  `continue-on-error: true` (defaults to false → required gate)
- summary job: now fails the run if docker-smoke is non-success
  (previously warning-only); message reflects three required gates
- inline doc on docker-smoke rewritten to reflect promoted-to-required
  state with run-history audit trail

EFFECTIVE FROM THIS COMMIT: a red docker-smoke now blocks the smoke
test summary, same as build-and-typecheck and release-assets-integrity.
Tagging a release with red docker-smoke is a process violation.

Risk: low. The Dockerfile is unchanged from the last 2 green runs.
This commit only changes CI gating semantics, not the build itself.
If this run goes red unexpectedly, revert the gate-change commit
(NOT the Dockerfile) and investigate.

-After 3 green: flip `continue-on-error: true` → remove that line in `.github/workflows/smoke-test.yml`. Update summary job to fail on docker-smoke red instead of warning.
+**Promotion changes** (single commit):
+- `.github/workflows/smoke-test.yml`: Removed `continue-on-error: true` from `docker-smoke` job (defaults to false = required).
+- `.github/workflows/smoke-test.yml`: Updated `summary` job's gate logic to fail if docker-smoke is non-success (previously warning-only).
+- Inline doc on docker-smoke job rewritten to reflect promoted-to-required state with run-history audit trail.
