Start by reproducing the launch failure on Arch Linux with `kiro-cli`, then run `q doctor` and `q restart` in the affected terminal session. Compare the resulting diagnostics or logs with the expected startup path; the issue is done when `kiro-cli` launches normally and the cause is covered by a verified fix.
