Neil 8d2f16856f fix(session): scope agent resume to the host that captured the session (#21288)
* fix(session): scope agent resume to the host that captured the session

A provider session id names a transcript in one machine's agent state
directory. Nothing in the resume path compared that machine against the
one the resume executes on, so a record captured on host A reached a
`--resume` run on host B, which answers `No conversation found with
session ID`.

Three things make the drift reachable: `worktreeId` is `repoId::path`
with no host component, sleeping records are `'sleepingAgentKeyed'` so
boot-time host-contention parking never arbitrates them and every
partition merges into one map without retaining provenance, and both
issuers resolve their launch target from the current catalog.

Both issuers are gated. The activation sweep hands `quit`/`live` records
whose pane still exists to the pane's own cold restore, so gating the
sweep alone changed nothing in the SSH lane.

Declines rather than guesses: the record is preserved and remains
resumable by hand. A refused resume is recoverable, a forked transcript
is not. The predicate fails open on anything it cannot positively rule
out -- an unstamped record, an empty stamp, or a `runtime:` host, which a
paired client uses to relabel its host's own SSH workspaces.

The cold-restore gate consults both the pane's transport and the
catalog. The transport alone was racy: it is unresolved on an early
reattach frame, and that frame is exactly when a wrong resume escaped.

* docs(session): name the inverted fail-open direction at the resume gate

* fix(session): keep an unresolved catalog out of the resume host verdict

The worktree form of the resume gate resolved the current host through
getExecutionHostIdForWorktree, which answers 'local' for a worktree the
catalog has no row for. Read as a host, that made every SSH-stamped record
look foreign until its repo row landed, contradicting the module's own
contract that it reports only a positively-known disagreement. Add
getKnownExecutionHostIdForWorktree, which returns null in that silence
(no repo row for a git worktree, no folder-workspace row for a folder
workspace), and route the gate through it; the pair form already fails
open on a null host. The routing resolver keeps its default unchanged.

The CI red on the control case was a separate spec race: the ledger wait
returned as soon as the ledger was non-empty, and it already held the
first launch's `--version` probe, so the control read two probes and gave
up before the cold-restore had typed `--resume` (the failure screenshot
shows the command running in the pane). The spec now reads only the lines
the relaunch appended, anchors on the relaunch's PTY binding and its own
probe, and then waits for `--resume` for the control case or a bounded
grace for the refusal case.
