fix(pm-bundle): drop dead shim check from payload smoke test

smoke-payload.sh's third check ran '../bin/hermes' — a self-relative CLI
trampoline minted only by the desktop release workflow
(build-bundled-desktop.mjs → mint-launchers.py). 'pm bundle --out' stages
repo+store+venv only, so the shim never exists and every pm-bundle lane
died at that check (exit 127) since the workflow's birth (Aug 28, same
error on every branch). Keep the real boot checks (store python imports,
hermes_cli entrypoint --version, pm doctor); drop the shim check.
