This commit updates the /bug command to point to the Qwen-Code
repository instead of the Gemini CLI repository.
The following files were modified:
- `packages/cli/src/ui/hooks/slashCommandProcessor.ts`: Updated the URL
for the /bug command.
- `packages/cli/src/ui/hooks/slashCommandProcessor.test.ts`: Updated the
test for the /bug command to reflect the new URL.
- `docs/cli/commands.md`: Updated the documentation for the /bug
command and replaced all instances of "Gemini CLI" with "Qwen Code".
