* feat(layout): read-only layout.subscribe stream and the round-trip self-check (inert) - layout.subscribe streams each workspace's layout as an explicit published projection (tabs, groups, panes and their terminals), never the model itself: no runtime records, closed-tab records, spawn inputs or legacy persistence values. It is re-projected from the Store's sessions after each write, only while someone subscribes, and only from the partition that owns each workspace. Not advertised as a capability and not on the mobile allowlist, so nothing calls it yet. - Replaces the unused terminal-topology publisher (#25682) it generalizes. - The round-trip self-check: a partition must load and save to a fixed point, changing only the kinds of value the Loader's rules change. It runs on Store writes in dev and e2e (logged, never thrown) and as the oracle's new roundTrip check. * fix(layout): know the spawn handoff main's minimal row mint stores * fix(layout): name-based invented ids, no partition on the wire, isolated listeners - Every id the Loader invents is derived from what it stands in for (a workspace's group from its key, a pane from its row or tab and position, a repeated tab id from its terminal), so removing an earlier workspace or tab no longer re-ids later ones. - The published layout no longer names its partition: the workspace key is the address and routing stays with the host; each tab still names the host that runs it. - One throwing stream listener no longer costs the others the event. - The self-check says plainly it is an idempotence check, and logs each new kind of first-load change with its count.
