v0.2.0

• Support running afmail in a subdirectory workspace rather than only the directory root, so a mailbox workspace can sit alongside other project files
• Collapse push into a single all-or-nothing operation that applies every pending real-mailbox effect together or none, removing partial-push states
• Add a draft show command to read a draft's full rendered content before sending, and simplify the overall draft workflow
• Unify message restore across lifecycles, make case reads work regardless of a message's lifecycle state, and allow adding a message straight into the archive
• Clarify CLI documentation and fix doc/code drift across file-formats, workspace, and code-structure docs
