[sergio-sisternes-epam]

Context

This issue tracks the remaining work for full Windows native support, following the completion of Phase 1 in PR #227 (issue #88).

Phase 1 - Completed (PR #227)

• All unit tests passing on Windows (1828 tests, 102 skipped)
• Windows binary builds and runs (apm.exe via PyInstaller)
• Cross-platform source fixes (38 source files, 15 test files)
• Windows CI added to PR pipeline (.github/workflows/ci.yml)
• Release pipeline already includes windows-x86_64 binary target

Phase 2 - Package Manager Distribution (This Tracking Issue)

Windows users expect to install CLI tools via native package managers. The release workflow (.github/workflows/build-release.yml) already contains scaffolded but disabled jobs for all three major Windows package managers. Each sub-issue below covers enabling one of them.
