chore: add RPM/DEB packaging artifacts — 5.10

3 packages: python3-meshbay-common (dep), meshbay-hub, meshbay-node.
RPM: spec files with pre/post scriptlets (useradd, systemd macros).
DEB: DEBIAN/control + postinst for hub, control for node + common.
Systemd: hub.service (system, security hardening) + node.service
(user template @%i, EnvironmentFile for MESHBAY_UNLOCK_KEY).
packaging/README.md: build + install instructions.
