- Add /mem0:dream --schedule support via Claude Code /schedule command with local launchd/cron fallback for non-cloud users - Add /mem0:digest --schedule and file output to ~/.mem0/weekly-digest.md with digest-history.log for trend tracking - Add on_post_commit.sh PostToolUse hook: interactive prompt after git commit asking user to save change as memory with category suggestion - Add on_bash_output.sh PostToolUse hook: detects stack traces and error patterns in bash command output, injects mem0 search rubric for prior occurrences (complements existing user prompt error detection) - Fix session-end report: now shows per-category breakdown "wrote 3 memories (decision 2, anti_pattern 1)" matching spec - Wire new hooks into all 3 platforms (Claude Code, Cursor, Codex) - Add post_commit and bash_error telemetry events - Add CTO demo testing guide with tier-by-tier manual test steps

# Hook: PostToolUse (matcher: Bash)
