v3.0.0 — Complete Feedback Implementation

All 6 items from memory-engine-feedback-v2.9.md implemented:

New Scripts:

• memory-resume.js — Zero-latency session recovery (<2000 tokens)
• memory-auto-extract.js — Mine session transcripts for events (OpenClaw format)

New Features:

• search --last N [--today] [--tag T] — Time-ordered recent entries without FTS5
• maintain --gc [--apply] — MEMORY.md stale entry detection & cleanup
• Write dedup — Skip entries similar to last 5
• Session size warning in boot.js + cron.sh (4MB/8MB thresholds)
• Flush prompt fix — Removed NO_REPLY escape, forces at least one write
• Cron: auto-extract from reset sessions + session size monitoring
