## Summary
- Preserve lftp stdout/stderr when the process exits non-zero.
- Surface bounded, whitespace-normalized diagnostics through the deploy
error.
- Redact FTPS host, username, password, path, URL userinfo, and encoded
secret forms.
## Verification
- `vitest run tests/unit/cpanel-deploy.spec.js` (25/25)
- `node --check scripts/release/cpanel-deploy-lib.mjs`
- `git diff --check`
This is the prerequisite diagnostic repair for failed Frontend Release
run 29854900889. Production was not switched during that failure.
