Adv 2.0 Phase L1: Babysit pivot + legacy resolver retire

Babysit pivots from harvest service to pet-care + safe-rest perk:
- runBabysitDaily/runAutoBabysitDay/runBabysitAction deleted; replaced
  by runBabysitDailyTrickle (3 pet XP/day while subscribed).
- BabysitSafeRest predicate promotes Standard camps to Fortified-tier
  rest (HP+1d6, threat -5, resources refresh) and reduces wandering
  monster check campMod from 0 to -4. Hooks live in
  dnd_expedition_camp.go and dnd_expedition_night.go.
- !adventure babysit auto/focus subcommands removed; status/purchase
  DMs reflect the new perks.

Scheduler drops the auto-babysit fallback block (no more silent
debits + harvest-day for missed logins). Babysit subscribers still
skip the morning DM; trickle runs in the background.

TwinBee daily simulator self-contained: simulateTwinBeeOutcome +
simulateTwinBeeLoot replace the resolveAdvAction call against a
fake CombatLevel=35 character. Outcome distribution and reward
shape preserved; gold-share to active players unchanged.

Legacy activity resolver retired: resolveAdvAction,
advEligibleLocations, AdvEligibleLocation, resolveAdvEmptyOutcome
deleted from adventure_activities.go (zero production callers
post-babysit/twinbee). AdvActionResult kept — combat_bridge still
produces it for arena/dungeon flows; dies in L2/L3.

Migration plan doc gogobee_legacy_migration.md added: five-phase
L1-L5 plan covering arena (Adv 2.0 boss flow rebuild), co-op
deletion, perk-gate sweep, and final teardown of AdventureCharacter
+ CombatLevel + combat_engine.
