C2(hephd-self-update): plan add goal + prerequisite cards for hephd self-update
Kick off the C2 Mikado chain for an opt-in (default-off) hephd
self-update mode (forge-poll -> cargo install from tag -> self-restart).
Goal card plus eight prerequisite cards, indexed from how-to.md:

  release-poll-version-check, self-update-opt-in-flag (leaves)
    -> self-update-poll-loop                 (notify-only core)
  service-env-forge-access (leaf, the cargo/forge blocker)
    + self-update-poll-loop -> cargo-install-from-tag
  service-respawn-on-clean-exit (leaf, systemd Restart=always)
    + cargo-install-from-tag -> self-restart-after-update
  verify-hub-dropout-resilience (leaf, lock in the base-case guarantee)

Grounded in research of hephd's sync loop, daemon lifecycle, the
launchd/systemd service templates, and the forge releases API.
