Fleet-polish bundle — boot-survival symmetry

From the Lead's Codex symmetry-gap finding. Three fixes completing add/remove boot-survival symmetry:

  1. disable-on-remove (bug). mosaic fleet remove stops + deletes roster/env/heartbeat but does NOT systemctl --user disable mosaic-agent@NAME.service — so a removed-but-enabled unit can resurrect on reboot pointing at deleted config. Add disable-on-remove (+ test).
  2. add-enable. mosaic fleet add should enable the new agent's unit for boot-survival.
  3. init-R5 guarantee. mosaic fleet init must guarantee exactly one orchestrator (hard-fail non-minimal mismatch instead of warning).
