fix(mode): an approved exit leaves plan mode at the step boundary, not mid-batch

Browse Source 
Review finding: the exit tool's direct mode/set append flipped the
folded mode while the loop could still execute further tool calls from
the SAME assistant response — a same-batch exit_plan_mode + write pair
would sail past tools/pre-execute under 'default' even though the
request was assembled under the plan-shaped header. That broke the
design's own invariant (a step's executions run under the mode its
assembly folded), which the pending-intent flush was built to hold for
user flips.

The tool now records the switch as a pending intent like every other
writer, flushed at this step's end (still in-turn); pending intents
carry a narrate flag so the exit's flush stays silent — the tool result
is its narration — while user flips keep the coalesced boundary notice.
The gate, folding the logged mode only, now provably covers the whole
batch: regression test pins approve-then-write-in-the-same-batch as
denied, and the widened toolset still arrives on the next step.

The recorded scenarios are re-recorded: the fixture now shows mode/set
landing after step/end, before the widened fallback header.
