[WIP] NPM publishing preparation

[tnaum-ms]

Work in progress: Preparing the repository for npm package releases.

Changes

Azure Pipelines (build + release)

• Replaced dummy pipeline stubs with real build and release configurations
• Build pipeline: packaging, testing, and artifact staging
• Release pipeline: validation and ESRP publishing steps
• .real backup files for pipeline configuration reference

Target package

This PR prepares the infrastructure to publish @microsoft/vscode-ext-react-webview to npm — webview infrastructure for VS Code extensions with type-safe tRPC RPC over postMessage, React hooks, and pluggable telemetry middleware.

Status

Once the pipelines are validated against @microsoft/vscode-ext-react-webview, other packages can follow the same pattern.

Note: we will not merge this PR. We're using it only to debug our release pipelines.
