[Bug] TAB completion for TUI options doesn't work

Description

The tab completions (powered by opencode --get-yargs-completions) doesn't recognize the "top-level" options intended for the TUI.
Additionally it shows a $0 as an option.
I.e. those here: https://github.com/anomalyco/opencode/blob/4a57013cf8cb163f58638273fd9da8538cd33cb7/packages/opencode/src/cli/cmd/tui.ts#L72-L143

That is an issue for something as common as opencode --continue

OpenCode version

1.18.13

Steps to reproduce

1. Setup bash completion: opencode completion >> ~/.bashrc
2. type opencode
3. Press TAB twice

$ opencode 
$0          acp         agent       attach      completion  db          debug       export      github      import      mcp         models      plugin      pr          providers   run         serve       session     stats       uninstall   upgrade     web   

Similar for options:

$ opencode --
--help        --log-level   --print-logs  --pure        --version  

Operating System

Linux Mint 22.3
