rightsize: trim over-provisioned memory (batch 2/N)

claude-agent-service 12Gi->3Gi (peak 585Mi — the single biggest fat, ~9Gi of limit-overcommit removed), job-hunter 1280->768Mi (kept chromium headroom; 30d peak 118Mi), fire-planner 1024->320Mi, wealthfolio 1Gi->512Mi (kept history-growth headroom). Burstable, limits kept >= generous peak headroom, never below peak. ~10.7Gi of limit overcommit removed. paperless-ai intentionally LEFT at 4Gi (documented in-process RAG model load).
