* feat(system-agent): hatch into the agent after a fresh setup applies
The hatch is a ceremony: a fresh-install setup apply now announces the hatch
and hands straight off (open-tui in the terminal, open-agent for gateway
clients); the web custodian page lands in agent chat with the birth-sequence
opener prefilled as a draft so one Send wakes the seeded BOOTSTRAP. Non-setup
persistent operations keep their in-place replies.
* fix(system-agent): hatch only on clean post-write verification
* fix(ui): scope hatch draft to setup handoffs
* fix(onboarding): seed hatch handoffs across clients
* fix(i18n): refresh native hatch inventory
* fix(onboarding): seed remote gateway hatch handoff
* fix(macos): localize hatch draft
* fix(onboarding): gate hatch on pending bootstrap
* fix(i18n): sync hatch source to ios catalog
* fix(onboarding): gate hatch on canonical pending state
