OpenSpec generates deprecated TOML commands for Qwen Code

[SemyonSinchenko]

It is also stated in the documentation of Qwen: https://qwenlm.github.io/qwen-code-docs/en/users/features/commands/#4-custom-commands

I think instead of

    getFilePath(commandId: string): string {
      return path.join('.qwen', 'commands', `opsx-${commandId}.toml`);
    },
    
    formatFile(content: CommandContent): string {
      return `description = "${content.description}"

in qwen.ts

it should be like

    getFilePath(commandId: string): string {
      return path.join('.qwen', 'commands', `opsx-${commandId}.md`);
    },
    
    formatFile(content: CommandContent): string {
      return `---
    description: ${content.description}
    ---

Based on the qwen documentation

Thanks for flagging this. This looks like a real Qwen Code compatibility issue, and we're going to queue it with the broader Qwen command-generation work instead of relying on Qwen's migration layer long-term.
