fix(terminal): suppress the whole saved startup set, not field by field

Round 4 self-check on my own round-3 fix. `suppressSavedStartup` guarded four of
the six values `connect` falls back to — `launchAgent` and
`startupCommandDelivery` still inherited from the transport's constructor. Adding
the guard per field is precisely how those two were missed, and the guarded
expressions had become unreadable.

The saved values are now one object that `suppressSavedStartup` drops wholesale.
A field added later is covered by construction rather than by remembering.

Found by asking the question the review lens was given rather than waiting for
its answer: does the suppression cover EVERY channel, or only the ones I noticed?
It did not.
