### Add PHP runtime PHM meter analyzer, e2e, and documentation
This PR adds OAP support for **PHP Health Metrics (PHM)** reported by the
SkyWalking PHP agent.
- Introduce `php-runtime.yaml` MAL analyzer registering six instance-level
meters on the **General Service** layer:
- `meter_instance_php_process_cpu_utilization`
- `meter_instance_php_memory_used_mb`
- `meter_instance_php_memory_peak_mb`
- `meter_instance_php_virtual_memory_mb`
- `meter_instance_php_thread_count`
- `meter_instance_php_open_fd_count`
- Add `php-runtime` to default `meterAnalyzerActiveFiles`.
- Pin `SW_AGENT_PHP_COMMIT` to merged PHM agent release `de311c9`.
- Set `metrics_report_period=31` in e2e `php.ini` so meter gRPC streams
idle-close and OAP persists PHM samples reliably.
PHM process meters are **Linux-only** (agent samples `/proc` via `getppid()`
for the parent PHP process).
- [x] If this is non-trivial feature, paste the links/URLs to the design doc.
- Agent-side PHM merged in apache/skywalking-php#145; no separate SWIP.
- [x] Update the documentation to include this new feature.
- `docs/en/setup/backend/dashboards-php-runtime.md`; update
`backend-meter.md`, `menu.yml`, and `CHANGES`.
- [x] Tests(including UT, IT, E2E) are added to verify the new feature.
- MAL data tests: `php-runtime.data.yaml`
- PHP e2e: six `meter_instance_php_*` assertions in
`test/e2e-v2/cases/php/e2e.yaml`
- Fork **Agent PHP** e2e passed before opening ([fork
run](https://github.com/songzhendong/skywalking/actions/runs/28111938023);
overall workflow may show red when unrelated e2e matrix jobs fail)
- [ ] If it's UI related, attach the screenshots below.
- Horizon UI widgets ship separately in `apache/skywalking-horizon-ui`.
- [ ] If this pull request closes/resolves/fixes an existing issue, replace
the issue number. Closes #<issue number>.
- [x] Update the [`CHANGES`
log](https://github.com/apache/skywalking/blob/master/docs/en/changes/changes.md).
