test: comprehensive coverage expansion for 1.9

Expand tests across three main areas:

1. **Host name/resolve tests** (10 new): auto-sequence naming,
   explicit override, whitespace rejection, UUID/name interchangeable
   lookup, suspend/resume/terminate via name, nonexistent error,
   resume-non-suspended no-op.

2. **Shared persistence suite** (14 new, shared by sqlite/postgres/
   in-memory): next_definition_sequence, get_workflow_instance_by_name,
   root_workflow_id round-trip, subscription token lifecycle, first
   open subscription, persist_workflow_with_subscriptions,
   mark_event_unprocessed, get_events filtering, batch
   get_workflow_instances, WorkflowNotFound, ensure_store_exists
   idempotency, execution pointer full round-trip, scheduled commands.
   Queue suite: 4 new. Lock suite: 3 new.

3. **Multi-step K8s integration test**: 4-step pipeline across 3
   different container images proving cross-image /workspace sharing
   through a SharedVolume PVC, bash shell override with pipefail +
   arrays, workflow.data env mapping, and output capture.

+## [1.9.0] - 2026-04-07
+
+### Added
+
+- **wfectl**: New command-line client for wfe-server with 17 subcommands
+  (login, logout, whoami, register, validate, definitions, run, get, list,
+  cancel, suspend, resume, publish, watch, logs, search-logs). Supports
+  OAuth2 PKCE login flow via Ory Hydra, direct bearer-token auth, and
+  configurable output formats (table/JSON).
+- **wfectl validate**: Local YAML validation command that compiles workflow
+  files in-process via `wfe-yaml` with the full executor feature set
+  (rustlang, buildkit, containerd, kubernetes, deno). No server round-trip
+  or auth required — instant feedback before push.
+- **Human-friendly workflow names**: `WorkflowInstance` now has a `name`
+  field (unique alongside the UUID primary key). The host auto-assigns
+  `{definition_id}-{N}` using a per-definition monotonic counter, with
+  optional caller override via `start_workflow_with_name` /
+  `StartWorkflowRequest.name`. All gRPC read/mutate APIs accept either the
+  UUID or the human name interchangeably. `WorkflowDefinition` now has an
+  optional display `name` declared in YAML (e.g. `name: "Continuous
+  Integration"`) that surfaces in listings.
+- **wfe-server**: Full executor feature set enabled in the shipped binary —
+  kubernetes, deno, buildkit, containerd, rustlang step types all compiled
+  in.
+- **wfe-server**: Dockerfile switched from `rust:alpine` to
+  `rust:1-bookworm` + `debian:bookworm-slim` runtime because `deno_core`'s
+  bundled v8 only ships glibc binaries.
+- **wfe-ci**: New `Dockerfile.ci` builder image with rust stable,
+  cargo-nextest, cargo-llvm-cov, sccache, buildctl, kubectl, tea, git.
+  Used as the base image for kubernetes-executed CI steps.
+- **wfe-kubernetes**: `run:` scripts now execute under `/bin/bash -c`
+  instead of `/bin/sh -c` so workflows can rely on `set -o pipefail`,
+  process substitution, arrays, and other bashisms dash doesn't support.
+
+### Fixed
+
+- **wfe**: `WorkflowHost::start()` now calls
+  `persistence.ensure_store_exists()`, which was previously defined but
+  never invoked — the Postgres/SQLite schema was never auto-created on
+  startup, causing `relation "wfc.workflows" does not exist` errors on
+  first run.
+- **wfe-core**: `SubWorkflowStep` now inherits the parent workflow's data
+  when no explicit inputs are set, so child workflows see the same
+  top-level fields (e.g. `$REPO_URL`, `$COMMIT_SHA`) without every
+  `type: workflow` step having to re-declare them.
+- **workflows.yaml**: Restructured all step references from
+  `<<: *ci_step` / `<<: *ci_long` (which relied on YAML 1.1 shallow merge
+  over-writing the `config:` block) to inner-config merges of the form
+  `config: {<<: *ci_config, ...}`. Secret env vars moved into the shared
+  `ci_env` anchor so individual steps don't fight the shallow merge.
+

+//
+// The tests above exercise the K8s step executor one step at a time. This
+// test drives a realistic multi-step pipeline end-to-end, covering every
+// feature that real CI workflows depend on:
+//
+//   * multiple step containers in the same workflow (different images
+//     per step so we can confirm cross-image sharing through the PVC)
+//   * a `shared_volume` PVC provisioned on the first step, persisting
+//     to every subsequent step
+//   * the `/bin/bash` shell override so a step can use bash-only features
+//   * `extract_workflow_env` threading inputs through as uppercase env
+//     vars to every step
+//   * `##wfe[output ...]` capture from a later step's stdout
+//   * a deliberate non-zero exit on a trailing step proving downstream
+//     error propagation
+//   * namespace lifecycle: created on first step, reused by all
+//     siblings, deleted at the end
+//
+// The pipeline simulates a tiny CI run:
+//
+//   1. `write-files`    (alpine:3.18)  → writes `version.txt` + `input.sh`
+//                                        to /workspace via `/bin/sh`
+//   2. `compute-hash`   (busybox:1.36) → reads files from /workspace,
+//                                        computes a sha256 with `sha256sum`,
+//                                        emits ##wfe[output] lines
+//   3. `verify-bash`    (alpine:3.18+bash) → uses `set -o pipefail` and
+//                                            arrays to verify the hash
+//   4. `inject-env`     (alpine:3.18)  → echoes workflow-data env vars
+//                                        (REPO, BRANCH) through outputs
+//
+// Without the shared volume, step 2 couldn't see step 1's files. Without
+// the shell override, step 3 would fail at `set -o pipefail`. Without
