test(e2e): add universal-core suite + CI

Mirrors pve-python e2e/ shape for the PDM cell. PDM-specific adaptations:
- `/access/ticket` returns `ticket-info` (PDM's stateful cookie marker), not
  a plain ticket — SC-14 skipped because the session cookie is HttpOnly
  server-set and not visible via the JSON API.
- POSIX character class regex workaround in conftest mirrors PBS — PDM
  models also use `[:cntrl:]` which Python's `re` can't evaluate.
- Token-auth probes use `/access/users` (token has no `/nodes` perms).
- int64 check probes memory counters (`free`/`total`/`used`) since PDM
  has no admin_datastore endpoint.

Scenarios: SC-01 (version), SC-10 (ticket-info), SC-11/12/13 (token auth),
SC-30/31 (user CRUD), SC-41 (input validation), SC-42 (no-ACL token),
SC-50 (int64), SC-51 (nullable). 11 passed / 1 skipped.

Local CI image is `pdm-test:latest` on port 8443.

+# E2E tests for `clientapi_pdm`
+
+Live-server pytest suite. Runs against a real Proxmox Datacenter Manager instance —
+by default the `ghcr.io/client-api/proxmox-docker/pdm-test` container, either
+spun up locally via `docker compose up -d` or in CI via
+[`client-api/proxmox-docker-action@v1`](https://github.com/client-api/proxmox-docker-action).
+
+## Quick start (local)
+
+```bash
+docker compose up -d
+sleep 20  # wait for healthcheck
+
+export PROXMOX_URL=https://localhost:8443
+export PROXMOX_USER=root@pam
+export PROXMOX_PASSWORD=proxmox123
+export PROXMOX_TOKEN_HEADER_VALUE="$(docker exec pdm-test cat /run/credentials.json | jq -r .token_header_value)"
+export PROXMOX_INSECURE=1
+
+pip install -e .
+pip install 'pytest>=8' 'pytest-timeout>=2.3' requests
+pytest e2e/ -v
+```
+
+## Scenario index
+
+Universal core scenarios that map cleanly to PDM:
+
+| File | Scenarios |
+|---|---|
+| `test_version.py` | SC-01 |
+| `test_auth.py` | SC-10 (ticket-info shape), SC-11/12/13 (PDM uses `:` token separator); SC-14 skipped (PDM cookie auth is HttpOnly server-set) |
+| `test_crud.py` | SC-30, SC-31 (user CRUD) |
+| `test_errors.py` | SC-41 (input validation), SC-42 (token without ACL) |
+| `test_types.py` | SC-50 (int64 memory counters), SC-51 (nullable) |
+
+PVE-specific scenarios (storage CRUD, ISO upload, VM/CT lifecycle, oneOf
+storage discriminator) do not apply to PDM — the suite reference for those
+lives in `pve-python/e2e/`.
+
+## Sibling suites
+
+`pve-python` is the canonical suite; `pmg-python` and `pdm-python` follow
+the same shape with per-product API and auth differences.
