fix conformance tests (#483)

# Fix conformance tests.

1. fix node version to workaround
https://github.com/nodejs/node/issues/56645
2. use `@argfile` to handle long classpaths
3. specify extension for npx for windows
4. Install `@modelcontextprotocol/conformance@0.1.8` GitHub Actions
workflow.
5. Centralize logging for process streams in conformance tests: Add
`startLogging` utility for InputStream logging with `KotlinLogging`.
Replace inline process stream handling with `startLogging` calls

Note: Currently tests pass using
`@modelcontextprotocol/conformance@0.1.8`/ But changing to 0.1.9 will
fail client scenarios (it is not related to this PR).

## Motivation and Context
Before fix conformance tests are broken on Windows

## How Has This Been Tested?
Run test locally and in github actions

## Breaking Changes
No

## Types of changes

- [x] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
