* fix: address pr-bug-scan validated finding from #6952 throwNodeNotFound() now re-raises AbortError when the shared signal is aborted, so a signal-cancelled node probe no longer launders into 'Node.js not found'; sequential fallback runs. * fix(ssh): make session-limited (MaxSessions=1) relay deploys actually succeed Review of #7180 verified the parent fallback end-to-end against a real MaxSessions=1 sshd and found the connect still failed. Four gaps, in order of discovery: - isSshSessionLimitError missed stock OpenSSH, which refuses session channels over MaxSessions with SSH2_OPEN_CONNECT_FAILED (2) and 'open failed' — reason 4 never matched, so the fallback never triggered. - execCommand settled aborted commands before the channel finished closing, so the sequential fallback reissued execs while sshd still counted the old session. - SshConnection.waitForSshCallback rejected aborts mid-channel-open immediately, leaking a confirmed-late channel that held the only session slot; it now settles after the late channel closes (bounded) and drains its streams so ssh2 emits 'close'. - Session channel opens now retry transient session-limit refusals (sshd frees the slot only after processing our close-ack, which the next open can beat by microseconds), and the remote orca CLI shim install is non-fatal like the managed-hook install — after the relay bridge occupies the sole session slot, raw-connection extras must degrade instead of failing the connection. Verified live against Docker sshd (OpenSSH 9.2, MaxSessions=1): fresh deploy (upload + native deps + launch), reconnect cycles, and a PTY round-trip all succeed; unrestricted-sshd regression run also passes.
