v0.4.2

Fixes the release pipeline so published releases actually carry downloadable binaries and a Docker image. No changes to the CLI or MCP server behaviour.

Customer-facing changes

• Release assets are now published: ado-mcp and ado-cli for Linux x86_64, macOS x86_64/arm64, and Windows x86_64, plus a multi-arch Docker image at ghcr.io/like-a-freedom/rusty-azure-devops (v0.4.0/v0.4.1 shipped no assets).

Fixed issues

• Release builds failed with cannot stat target/.../release/rusty_azure_devops — the package ships two binaries (ado-mcp, ado-cli), and the workflow now publishes both for every platform.
• The Docker image build failed at cargo fetch; the build stage now creates placeholder targets before fetching dependencies.
