Phase 14: B-002 pre-fix RPC repro — filter snapshots and readSettings fix

RPC E2E with debug shows registered present at session_compact but planned=[]
because kept still contains the skill block; registered=[] still drops skills
absent from kept. Sync file readSettings avoids RPC hook deadlock on
SettingsManager/isProjectTrusted.
