feat: implement CI pipeline (Jenkinsfile) for 001-ci-pipeline

Implements tasks T001-T016, T018-T022, T024-T026 from
specs/001-ci-pipeline/tasks.md (T017/T023 need a real Jenkins
instance to verify and are left for manual follow-up).

- Add Jenkinsfile: checkout -> install -> environment validation
  -> typecheck -> lint (+ architecture check) -> format check ->
  unit -> integration -> E2E -> build -> Docker build -> publish
  -> deploy, matching the constitution's required stage order.
  Secrets are always injected from Jenkins credentials at runtime,
  never read from a repo-committed file. Publish/Deploy are skipped
  (not failed) on branches with no resolved deploy target.
- Fix docker-compose.test.yml: remove fixed container_name on
  app/postgres/redis, which would have made concurrent CI runs
  collide (FR-009). Verified locally that two runs under different
  -p project names no longer share container/volume/network names.
- Document the pipeline and local .env setup in README.md.
- Mark completed tasks in specs/001-ci-pipeline/tasks.md and record
  the container_name/compose-down-env-file findings in the spec's
  requirements checklist notes.

Locally verified passing: Dockerfile build, typecheck, lint,
architecture check, format check, unit test suite, and the edited
docker-compose.test.yml bringing up postgres/redis with isolated
per-project container names.

+## Implementation notes (added during /speckit-implement)
+
+- `docker-compose.test.yml` had fixed `container_name` values (`support-test`,
+  `postgres-test`, `redis-test`) on all three services — this would have made FR-009/SC-005
+  (concurrent-run isolation) impossible, since Docker container names must be unique per host
+  regardless of Compose project. Removed them so Compose auto-names containers per project
+  (verified locally: two `up` runs under different `-p` project names now produce
+  `<project>-postgres-1` / `<project>-redis-1` etc. with no collision).
+- `docker compose ... down` needs the same `--env-file` flag as `up`, or it can fail to resolve
+  service config and leave containers running — confirmed by hitting this locally; the
+  `Jenkinsfile`'s `post { always { ... } }` teardown includes it.
+- The existing `test:unit` npm script (`vitest run` with no path filter) currently runs the
+  entire `tests/**/*.test.ts` glob — including integration/E2E — because `vitest.config.ts`'s
+  `include` isn't scoped per script; only `test:integration`/`test:e2e` narrow by passing an
+  explicit directory. Today's "integration" tests are instantiation-only checks (no real DB/Redis
+  calls yet), so this isn't currently harmful, but it means the `Unit test` stage doesn't
+  actually isolate unit-only coverage. Out of scope to fix here (not part of this feature's
+  requirements) — worth a follow-up once real integration tests exist.
