Phase 1 — index at startup: ao inject --index-only renders a compact
table (~200 tokens) instead of full content (~800 tokens). Enabled via
AGENTOPS_INDEX_INJECT=1 feature flag in session-start.sh.
Phase 2 — on-demand pull: ao lookup <id> fetches full content by ID,
ao lookup --query "topic" searches by relevance, ao lookup --bead ag-xyz
filters by source bead lineage. Records "pulled" citations for MemRL.
Also: remove 3 unused test helpers (writeGoalsMD, setupRatchetChain,
setupAgentsDirs) to fix lint, add prune policies for evolve/vibe/crank/
brainstorm/local-ci directories, update skills and docs.
