v0.2.0 -- Ground Truth

Ground Truth

This release prioritizes honesty over feature claims. Commands either work or tell you they can't.

Breaking Changes

• mocker create, rename, pause, unpause now return explicit unsupported errors instead of silently mutating local metadata
• mocker login / logout now return unsupported error (credentials were never consumed by pull/push)
• Unsupported flags in mocker run now produce stderr warnings

Security Fixes

• Fix shell injection in copyToContainer -- replaced sh -c with stdin pipe to tee
• Fix shell injection in compose hostname injection -- same pattern
• Fix pipe-buffer deadlock in both paths (async terminationHandler instead of blocking waitUntilExit)

Flag Forwarding

• Forward Apple CLI flags in mocker run: -i, -t, -c, -m, --label, --cidfile, --rm, --tmpfs, --dns-search, --dns-option, --platform
• Forward Apple CLI flags in mocker build: --label, --quiet, --progress, --output
• Fix hostname parser (use assigned name, not inspect hostname field)

Documentation

• 12 commands marked [unsupported] in COMMANDS.md
• Compatibility notes added to both READMEs
• Feature claims qualified ("Docker CLI compatible" not "full compatibility")

Testing

• ProcessRunner protocol + MockProcessRunner actor for testability
• 16 new tests (42 total, was 26)
• ContainerEngine, ComposeOrchestrator, and flag enforcement tests

Other

• All version strings unified via Version.currentVersion
• Volume list prunes stale entries where _data/ directory no longer exists
