Merge Sim 434a829035 fix(orchestration): stop three PTY-only probes answering for structured sessions
Three defects, one shape: a probe that enumerates PTYs or resolves a pane was
standing in for a question that is not about panes at all.

`worktree rm` destroyed a live structured worker. `killAllProcessesForWorktree`
sweeps the renderer graph, the provider session list and the local pty-registry,
and a structured session is registered on none of them — so all three counted
zero, nothing errored, and removal deleted the checkout out from under a running
provider child, which kept running with its `cwd` gone while the dispatch still
reported the worker live and exact. A fourth sweep now asks what the other three
cannot: membership by `location.workspaceId`, which covers a plain chat session
as well as a dispatched worker, and liveness by the same
`live`/`unverifiable`/`exited` observation the rest of the structured surface
uses. It REFUSES a destructive removal rather than auto-closing, on the same
bargain and the same `--force` escape hatch as the unstopped-PTY gate — this is
the verb that deletes a user's work, and a running agent is exactly what they
would want to be told about. Force closes the sessions properly instead of
orphaning a child. Best-effort reconciliation callers are excluded: they repair
state, delete nothing, and must never be failed closed.

Twelve coordinator verbs failed for a structured worker running as itself.
`isLiveTerminalHandle` validated `ORCA_TERMINAL_HANDLE` with `terminal.show`, a
PTY verb whose leaf lookup misses for a session that never had a pane; the pane
remint that would have recovered it needs `ORCA_PANE_KEY`, which a structured
child deliberately does not carry, so every one of them died on
`no_active_sender_terminal` — including the ones the worker's own dispatch
preamble tells it to run. The identity question gets its own probe,
`terminal.resolveIdentity`: a handle and a boolean and nothing writable.
`terminal.show` still refuses a structured handle, because synthesising
ptyId/leafId/paneRuntimeId would hand every public terminal verb something that
looks writable and is not. The PTY half is byte-for-byte today's check,
`getLiveLeafForHandle` included, so its `rendererGraphEpoch` re-check still runs
— that check is the whole reason the sender is validated at all, and a cheaper
probe would have quietly started passing stale post-reload handles. A host that
predates the method answers `method_not_found` and the client falls back to
`terminal.show`, which is correct for that host: one without the identity probe
has no structured workers to miss.

`dispatch --inject` reported `no_agent_detected` for a structured worker, because
`isTerminalRunningAgent` reaches `getLiveLeaf`, throws, and the catch returns
false. A structured session IS the agent; there is no foreground process to
recognise, so it answers before the PTY probes rather than through them.

Also: a Run whose coordinator is structured now gets its `run:` mail. Both lanes
declined and neither logged — the PTY lane because the owner is structured, the
structured lane because the mailbox was not `dispatch:` — so each half believed
the other owned it. The PTY lane's reasoning (a coordinator blocks in
`check --wait`, where a waiter preempts pointer delivery) does not transfer: a
structured coordinator is a chat session whose turn ends. Its `run:` deliveries
take the `hasOutstandingRunDelivery` gate the PTY lane applies for exactly that
mailbox, and only for that mailbox.

The test that would have caught the twelve drives the CLI with
`ORCA_TERMINAL_HANDLE=structworker_…` and no `--from`. Every existing
orchestration CLI test passes `--from` explicitly, so the resolver a real worker
goes through was never exercised — which is why the suite stayed green while the
preamble failed on its first line.

Two files crossed their line ceiling and are split rather than waived:
`worktree-teardown.ts` sheds its two PTY-surface sweeps and the deadline
arithmetic they share, and `orchestration.test.ts` — which sat exactly on 800 —
sheds the two caller-identity suites this change rewrote.
