Garry Tan 7172309d44 feat: bidirectional learnings bridge — gstack writes OpenClaw memory files
When ~/.openclaw/ exists, gstack-learnings-log writes a parallel markdown
copy to ~/.openclaw/workspace/memory/gstack-{slug}.md. OpenClaw agents
can read these directly as memory entries.

gstack-learnings-search reads back from OpenClaw memory files (*.md in
~/.openclaw/workspace/memory/) and includes them in unified search
results alongside native JSONL learnings. Cross-pollination.
