v0.6.0

CLI redesigned around AppFlowy's workspace → space → page hierarchy.

appflowy-cli use test                 # default workspace, kubectl-style
appflowy-cli ls demo                  # browse by path
appflowy-cli export demo/notes -o note.md   # leaf page -> .md
appflowy-cli export demo -o ./demo          # space -> directory
appflowy-cli export -o ./backup             # whole workspace
appflowy-cli import demo ./notes            # dir -> subtree, file -> page
echo "# Note" | appflowy-cli save demo "Title"

• PATH segments are names or UUIDs, resolved level by level against each parent's children — duplicate names in different spaces don't collide, and a miss lists the actual children
• -w <workspace> overrides the default per command; workspaces stars the default
• One export and one import replace the five flat export-*/import-* commands (breaking change)
• import/save refuse the workspace root, where a page would silently become a space

No MCP tool changes (still 73 tools).
