When the user invokes /project, determine the subcommand from context:
/project new <name> → Call athena_project_create with the name. Ask for description and optional directory.
/project list → Call athena_project_list
/project open <query> → Call athena_project_open with the search query
/project advance → Call athena_project_advance for the current project. Confirm the phase transition first.
/project scan → Call athena_project_scan for the current project
/project (no subcommand) → Show available subcommands
