v0.4.4

Highlights

• Stable folder reads and safer nested-folder management.
• Multi-folder message location tracking and verified, retry-safe moves.
• Bulk mutations above 50 messages now require --execute; drafts remain safe previews.
• read changes local agent-read state only with --mark-agent-read.
• Added a signed local macOS install workflow for stable Keychain access.

This source release supports Homebrew builds. For a personal signed install, run scripts/install-signed-local.sh from the checkout.
