Long expeditions D4-a: autopilot DM bundling + EoD digest

Suppress per-tick auto-walk DMs in compact mode. tryAutoRun now only
surfaces for fork / death / run-complete / boss-safety camp / Night-camp
pitch. A Night-camp pitch flushes the day as an EoD digest (counts of
walk/harvest/interrupt plus threat/milestone/narrative bullets, built
from dnd_expedition_log) followed by the camp block. Each successful
background walk writes a `walk` log entry so the digest can count rooms
without persisting raw stream narration. maybeAutoCamp and
pitchBossSafetyCamp now return the autoCampDecision so callers can
branch on dec.Night.
