Add `attach_bottled_agents_to_gateway()` as an `@abc.abstractmethod` on `BottleBackend` and implement the first reconcile step across all three backends: on a gateway cold boot, replace every already-running agent's trusted CA with the freshly-minted gateway CA. Reconciling running bottles is a backend responsibility (only the backend can enumerate its agents and reach them — firecracker over SSH, docker/macOS over exec/cp), so making it an abstract method keeps the fix cross-backend by construction. The gateway rootfs is ephemeral, so a rebuild mints a new CA that every running bottle distrusts (SSL verification fails — #510). This reconcile is what distributes the fresh CA, so a routine gateway rebuild now doubles as a free CA rotation. Per-bottle steps are best-effort: one unreachable or malformed bottle is logged and skipped, never blocking the others. Trigger — `Gateway.connect_to_orchestrator` now returns a cold-boot bool (True when it actually (re)brought the gateway up, False when a healthy current gateway was left untouched); each infra `ensure_running` gates the reconcile on it, so it fires exactly on cold boot and never on an adopt. Git-gate re-provision and egress-token restore fold into this same reconcile on the same trigger in follow-up PRs (#516). Refs #516. Addresses #510.
