infra: CI/CD pipelines (lint, test, release)

[kristopherjturner]

Overview

Implement CI/CD pipelines for linting, testing, and releasing the VM Conversion Toolkit. Pipelines enforce PowerShell code quality gates on every PR and produce versioned release artifacts.

Scope

• GitHub Actions workflow: PSScriptAnalyzer lint on all .ps1 files
• GitHub Actions workflow: Pester unit tests with coverage report
• GitHub Actions workflow: Release Please for automated changelog and release notes
• Release artifact: ZIP of scripts/ and config/ with version tag
• Dependabot for workflow and module dependency updates
• Branch protection: require lint + test passing before merge

Acceptance Criteria

• PSScriptAnalyzer lint runs on every PR with zero errors (warnings reviewed)
• Pester tests run in CI without cluster access (mocked cmdlets)
• Coverage report posted as PR comment
• Release Please creates release PRs on merge to main
• GitHub Release includes versioned ZIP artifact

Dependencies

• Parent Epic: [Epic] VM Conversion Toolkit Full Build-Out #5
• Pester test coverage: feat: Pester test coverage for all conversion scripts #8
• IaC maturity tracking: Track IaC tool maturity status across all repos (Built / Tested / Released) azurelocal-toolkit#5
