[ci-scan] Build break: SOS.Tests receives unsupported --method option

## Build Information

Build: https://dev.azure.com/dnceng-public/public/_build/results?buildId=1580049
Build error leg or test failing: `SOSTests / {DAC,cDAC,cDAC_verify}_windows_x64_release / Build / Test` - `SOS.Tests`
Pull request: https://github.com/dotnet/runtime/pull/133143

KBE authoring guidance (ci-failure-scan)

- `Error Details` is for readers. Build Analysis parses only the JSON block under `Error Message`.
- The ordered signature below was copied from each failing `SOS.Tests_net10.0_x64.log`.
- `BuildRetry` is false because the same deterministic argument error occurred in all three legs.

## Error Details

```text
"SOS.Tests.exe" -method SOS* ...
Unknown option '--method'

The runner's help lists --filter-method. No SOS test executed and no SOS test-result file was generated.
```

Affected legs:

- `DAC_windows_x64_release`
- `cDAC_windows_x64_release`
- `cDAC_verify_windows_x64_release`

## Error Message

```json
{
"ErrorMessage": [
"SOS.Tests.exe\" -method SOS*",
"Unknown option '--method'"
],
"ErrorPattern": "",
"BuildRetry": false,
"ExcludeConsoleLog": false
}
```

Agentic workflow metadata (ci-failure-scan)

Workflow artifact: ci-failure-scan
Artifact kind: kbe-verification
Verified match count: 3 hits across the three failure logs; each array element matched once per log and matched no PASS or SKIP line.

**Recommended action:** Update the SOS method-filter translation for the current test runner (`--filter-method`) or otherwise restore compatibility with the existing diagnostics pipeline filter.

### Report
#### Summary
|24-Hour Hit Count|7-Day Hit Count|1-Month Count|
|---|---|---|
|0|0|0|

Start with the SOS.Tests.exe invocation in the failing SOS.Tests_net10.0_x64.log and compare the diagnostics pipeline's method-filter translation with the runner help, which lists --filter-method. Re-run the affected DAC, cDAC, and cDAC_verify Windows release test legs; done means the unsupported-option error is gone and SOS test results are generated.
