Add CLI multi-project commands and --project flag support.

New commands:

• kb project list [--json] — List all registered projects with task counts and health
• kb project add [name] [path] [--isolation <mode>] [--interactive] — Register a project
• kb project remove <name> [--force] — Unregister a project
• kb project show <name> — Show project details with health and task counts
• kb project info [name] — Alias for show command
• kb project set-default <name> — Set default project
• kb project detect — Detect project from current directory

All task and settings commands now support --project <name> flag:

• kb task list --project myapp
• kb settings --project myapp

Projects are auto-detected from cwd by walking up to find .fusion/.
