Merge Sim

An ordinary structured chat session — not a dispatched worker — is spawned with no `ORCA_TERMINAL_HANDLE`, because `structuredWorkerChildIdentityEnv` early- returns for any session outside the worker registry. `orca orchestration check` then fell through to `terminal.resolveActive`, which picks the focused tab's active leaf or the first leaf in the worktree. It returned a valid handle, so nothing errored — and `check` is destructive by default, so it consumed another pane's oldest unacknowledged batch and marked it read. The rightful worker never saw that mail. `requireUnambiguous` does not fix this, only narrows it: it refuses when MULTIPLE leaves could be meant, and with exactly one terminal pane in the worktree the guess still resolves — to a sibling. "One terminal pane plus one chat tab" is a normal layout, so the common case stayed broken. The pinned test is that case. So the child now carries `ORCA_STRUCTURED_SESSION`, and every remaining route that would GUESS an implicit terminal refuses on it with an error naming the flag to pass. The marker names NOTHING — no handle, no pane key, no session id, no token — which is the whole reason it is safe: it cannot be replayed, cannot impersonate, and cannot flow into the hook-attestation, agent-row or mobile-projection pipelines the way a pane key would. That makes it a different decision from withholding `ORCA_PANE_KEY`, not a reversal of it. It also grants no CLI reachability, so packaged builds keep exactly today's exposure. The comment at `orca-runtime-adopt-terminal-orphans-from-inventory.ts` that justified the guess — "a structured worker is covered instead by the `ORCA_TERMINAL_HANDLE` its child is spawned with" — was true only for dispatched workers and false for every other structured session, a population this branch creates. It now says which case it covers and which case it does not.
