After #5239 compaction, a later render only fills segments from
#compactedChildStart, leaving undefined holes in the prefix. Iterating
those entries crashed when retiring IRC/ephemeral cards
(`segment2.component`). Guard undefined segment slots and cover the
sparse-hole path with a red/green regression.
Applied explicit thinking suffixes from matching configured model roles when the temporary model picker switches the session model.
Added regression coverage for the Alt+P temporary picker resolution path.
