v5.0.2

Fixes duplicate quota slash commands in the TUI.

The CLI/TUI plugin no longer registers slash names for its keymap commands; slash names are owned by the server command catalog. OpenCode's prompt autocomplete merges keymap slash names with the server catalog without deduping, which listed every quota command twice. The command palette (Ctrl+P) entries keep the TUI dialog and argument-prompt behavior, while the quota and token report commands now resolve once through the server catalog. Web and Desktop clients are unchanged.

Also fixes the packed-package smoke assertion to use the actual @Cardinal4 scope.

Tested against OpenCode 2.0.11.
