Collapse null pyworker client to a single mode parameterized by --count

Now that the session model means no HTTP connection is held during the
reservation, the dichotomy between "single reserve" and "trapezoid demo"
collapses — both are "open N sessions, each held for H seconds, started
I seconds apart, close." Replace --reserve/--demo/--duration/--plateau
with --count/--hold/--interval. --session-cost becomes --cost.

Client is now 64 lines (down from 120).

+# Null PyWorker
+
+Holds Vast Serverless reservations open without forwarding any work to a
+model. Use it when your real workload (a queue consumer in any language)
+runs as a separate process on the instance and you just want to drive
+Vast autoscaling: **one POST reserves a worker, one POST releases it.**
+
+## Use case
+
+You have a job queue on your own infrastructure (Redis, SQS, NATS, etc.)
+and a consumer (node, golang, python, a binary — anything) that pulls
+from it. You want one Vast worker per unit of in-flight work, scaling
+elastically from zero. The null PyWorker is the autoscaling driver; your
+consumer does the work.
+
+## How it works
+
+Reservations use the framework's session API. The SDK's
+`endpoint.session(...)` POSTs `/session/create` to reserve a worker;
+`session.close()` POSTs `/session/end` to release it. `max_sessions=1`
+means each worker holds exactly one reservation — the next reservation
+either lands on a free worker or triggers a scale-up.
+
+The PyWorker itself does nothing functional:
+
+- One trivial `/ping` route to satisfy the framework's benchmark
+  requirement (its `max_perf` is pinned to 100).
+- An internal `/release` endpoint on `127.0.0.1:18999` for the local
+  consumer to end the session without needing `session_auth`.
+
+## Endpoint parameters
+
+Tested working configuration:
+
+| Parameter | Value | Why |
+|---|---|---|
+| `target_util` | `1.0` | One session = one worker. Default `0.9` rounds up to an extra worker. |
+| `min_load` | `0` | Scale-to-zero floor. |
+| `max_queue_time` | `1` | Stop routing to an occupied worker after ~1s of implied queue. |
+| `target_queue_time` | `0.5` | Trigger scale-up promptly once anything queues. |
+| `inactivity_timeout` | `10` (seconds) | Permit scale-to-zero after 10s idle. |
+
+## API
+
+| Route | Where | Use |
+|---|---|---|
+| `POST /session/create` | endpoint, signed | Reserve a worker (`endpoint.session(...)`) |
+| `POST /session/end` | endpoint, signed | Release (`session.close()`) |
+| `POST /release` | `127.0.0.1:18999`, no auth | Local consumer release, no `session_auth` needed |
+
+## Healthcheck
+
+Default: stub on `127.0.0.1:18999/health` returning `200`. Set
+`BACKEND_HEALTH_URL=http://127.0.0.1:9090/health` (absolute URL) to point
+the framework at your queue consumer's health endpoint instead — if the
+consumer dies, the autoscaler sees the worker as broken.
+
+## Deploying
+
+1. Point `PYWORKER_REPO` at this repo (or your fork).
+2. Set `BACKEND=null` in the template.
+3. Run your queue consumer alongside the PyWorker. When it's done with
+   a unit of work:
+   ```bash
+   curl -X POST http://127.0.0.1:18999/release
+   ```
+
+## Client demo
+
+```bash
+# Single reservation, hold 180s
+python -m workers.null.client --endpoint <NAME> --instance alpha
+
+# Three concurrent reservations, started 30s apart, each held 360s
+python -m workers.null.client --endpoint <NAME> --instance alpha --count 3 --hold 360
+```
+
+Flags: `--count` (number of concurrent sessions, default 1), `--hold`
+(seconds each session is held, default 180), `--interval` (seconds
+between starts when `--count > 1`, default 30), `--cost` (cost reported
+at session-create, default 100 = `max_perf`), `--instance` (`prod` |
+`alpha` | `candidate` | `local`).
+
+## Environment variables
+
+- `BACKEND_HEALTH_URL` — absolute URL the framework healthchecks. Stub
+  is used when unset.
+- `NULL_CONTROL_PORT` — internal control server port. Defaults to `18999`.
