v0.0.2

Muamba v0.0.2 adds platform-aware vendoring and a verified integrity-addressed cache.

Highlights:

• exact GOOS/GOARCH download variants with runtime or explicit target selection
• atomic all-variant lock and update operations with selected-target materialization
• executable mode and per-download size controls
• SHA-384-addressed cache with offline all-platform verification
• target-aware Go resource generation and exported resource hashes for cache busting
• --target, --cache-dir, MUAMBA_CACHE_DIR, and verify --all-platforms

HTTPS remains the default. HTTP and insecure TLS continue to require explicit opt-in.
