feat(resource-value-verification): extend xce-deploy-ha with apiserver step + start-all.sh (task 3.1)

deploy-ha.sh Step 3 gains an opt-in-by-presence apiserver step (gated on a
pre-built /tmp/apiserver binary, not built by this script) that generates
start-apiserver.sh with a debug-level logger.yaml, plus an always-generated
start-all.sh sequencing controller-health-check-then-worker/scheduler
(-vvv)/apiserver. Purely additive - callers without a built apiserver
(e.g. xce-test-ha) see zero behavior change.

Live-confirmed both scenarios end-to-end: no-apiserver correctly skips the
step; with-apiserver reaches full backend registration with debug logging
active and scheduler emitting DEBUG3 output.

`cluster.bin` from `src/configs/*.yaml` fresh on every deploy
- `openssl` must be on `PATH` (provided by `nix develop`) — `deploy-ha.sh`
generates a fresh self-signed TLS cert/key for every deploy
- Optional: run `cd src/frontend && make build-server` first if you want an
apiserver step (Step 4d) — a separate Go build system from the meson build
controller/worker/scheduler share, producing `/tmp/apiserver`.
`deploy-ha.sh` never runs this itself; without it, Step 3 simply skips
generating `scripts/start-apiserver.sh` (soft-skip, not an error), same as
the existing worker/scheduler convention.

directly into the deploy dir (`$TOP`) by `deploy-ha.sh` itself, not read from

`--controller` silently tried port 9991 and failed with a connection-

## Step 4d — Start the apiserver (optional)
`deploy-ha.sh` also generates `$TOP/scripts/start-apiserver.sh` **if** a
pre-built apiserver binary exists at `/tmp/apiserver` (soft-skipped with a
warning, not a hard error, if missing — see Prerequisites). Start it once at
least one controller is up, the same way as the worker/scheduler:
```bash
"$BASH_BIN" "$TOP/scripts/start-apiserver.sh" &
```
- Runs the apiserver binary with `-d "$TOP/apiserver"` as its top directory,
pointing it at `$TOP/apiserver/config/{app.yaml,auth.yaml,rbac.yaml,logger.yaml}`
— a **minimal boot-only config**, not a production one:
- `auth.yaml`/`rbac.yaml` are copied verbatim from the repo's own shipped
dev-mode templates (`src/frontend/apiserver/config/`) — functional
auth/RBAC is not required for this deployment (no REST query is ever
issued against it here), only enough to load without erroring.
- `app.yaml` is copied from the same shipped template, with its
`backend:` section replaced to point `peers:` at this deployment's own
`ctrl-N=host:port` candidate list (the same one every other generated
script here already uses) — without this, the apiserver never connects
to the controller at all.
- `logger.yaml` is generated fresh (not copied) with `logging.level:
debug` explicitly set — required for any future apiserver-side
trace-log observability to actually be emitted; at any less-verbose
level it is silently dropped.
- Logs to `$TOP/logs/apiserver.log` — same shared `logs/` directory
`ctrl-N.log`/`scheduler.log` already use (an absolute `outputPath` in
`logger.yaml`, even though the apiserver's own topDir is the separate
`$TOP/apiserver`).
- Verify it started and connected to the controller:
`grep "Backend connection registered" "$TOP/logs/apiserver.log"`.
- Does not attempt HA/multi-instance apiserver deployment — single instance
only.
## Step 4e — `start-all.sh`: Steps 4/4b/4c/4d in one shot
`deploy-ha.sh` **always** generates `$TOP/scripts/start-all.sh`, a combined
shortcut that automates the manual recipe above end to end:
```bash
"$BASH_BIN" "$TOP/scripts/start-all.sh"
```
It: starts every controller node (`start.sh ctrl-N -vvv`, staggered 0.5s
apart, same as Step 4); waits up to 30s for the same primary-election
health-check Step 5 checks for; then starts whichever of
`start-worker.sh`/`start-scheduler.sh`/`start-apiserver.sh` were actually
generated for this deploy — checked via `[ -x ... ]` at `start-all.sh`'s own
runtime, so it correctly skips any step whose binary wasn't built, with no
regeneration needed. The scheduler is started at `-vvv` specifically (not
just `-v`) so its `TRACE`/`debug3`-level output is reliably emitted. Every
process is backgrounded via `setsid nohup … </dev/null >/dev/null 2>&1 &
disown`, so the whole cluster survives `start-all.sh`'s own exit — safe to
run from a subagent dispatch the same way Steps 1–5 already are (see the
note at the top of this file).
`start-all.sh` is regenerated fresh on every Step 3 deploy, same as every
other generated script — nothing to keep in sync by hand.
## Step 5 — Verify cluster health

## Implementation Notes
- Task 1.1: `resval_typeresolve.c`'s new function is `int resval_resolve_type(const char* name, int type_override)`, returning a `Value_u_which` tag or `RESVAL_TYPE_UNKNOWN` (-1, doesn't collide with the real 0-6 enum range). Task 2.1 should build on this exact signature rather than inventing a new one. `test.c`'s `set_resval()`/`cmd_resupdate()` were deliberately left untouched by task 1.1 — task 2.1 is the one that makes `set_resval()` a thin wrapper.
- `controller_unit_test` (the big legacy Unity binary) has a pre-existing, unrelated flaky failure in `test_config_repl.c` (bug-1561, overlayfs `fdatasync errno=5` sandbox artifact) that shows up on every `/xce-build controller` run in this environment. It is NOT caused by this feature's changes — do not chase it in later tasks; cross-check `.wolf/buglog.json`'s bug-1561 entry before treating a `controller_unit_test` failure as real, and confirm via `git status` that `test_config_repl.c`/`config_repl.c` are untouched by the current task's diff.
- Task 3.1: `src/frontend/Makefile`'s `build-server` target does not work standalone in this environment — it never sets `CGO_CFLAGS`/`CGO_LDFLAGS` the way `test-backend` does, failing with `fatal error: client.h: No such file or directory`. Pre-existing, out-of-boundary for this feature (confirmed unrelated to any of this feature's changes). To build a real apiserver binary for a live smoke test, export the same CGO flags `make test-backend` derives before running `go build`. Worth a separate bug-log entry / follow-up fix to the Makefile itself, not fixed here. Also found and worked around (config-only, no source change): `main.go`'s `RegisterToBackend` gate checks `BackendYamlConfig.Address` before consulting `Peers`, so a generated config needs `address`/`port` populated from the first `--peers` candidate, not just `peers` itself (bug-1571).
- Task 2.2: `src/controller/meson.build` compiles `test.c` only into the `xce_test` binary (`xce_test_src`), never into `controller_unit_test` (`controller_unit_test_src`) — a `test.c`-only diff structurally cannot regress `controller_unit_test`'s results. Also: `controller_unit_test` is built with ASAN `detect_leaks=0` as pre-existing, repo-wide meson policy (not something any task in this feature turned off) — to actually check a `test.c` change for new leaks, run `xce_test` directly with leak detection left ON, don't rely on the meson suite's leak-detection status.
- Task 2.1 (round 1 REJECTED, round 2 fixed): refactoring a getopt-loop's flush/finalization timing (needed to let a trailing flag like `-t` apply to its preceding `-n`/`-v` pair) can silently drop an unrelated existing guard (here: duplicate-`-v` rejection) that depended on the old immediate-finalization timing. When touching `cmd_resupdate()`-shaped CLI parsers in this codebase again, explicitly re-trace EVERY branch of the old getopt loop against the new one, not just the branches directly related to the new flag — a "traced every path" claim is only as good as the list of paths actually enumerated. `xce_test` also needs `ASAN_OPTIONS=detect_leaks=0` for reliable non-interactive stdin-piped smoke testing (its default leak-detection exit path can swallow buffered stdout).
