feat: scaffold redsen-lean-harness v0.1.0

Recovered from crashed session (Node OOM). Repo contains full P0-P6
scaffold: plugin.json/marketplace.json, AGENTS.md, ADRs 0001-0006,
lh CLI (init/index/graph/lane/run/memory/host/report/doctor), 10
.github/agents, 12 CLI skills, instructions, context7 mcp.json, and
unit/e2e test suite.

Fixed: run.mjs read --in-tokens/--out-tokens but tests and CLI docs
use --input-tokens/--output-tokens, so telemetry totals were always 0.
Now accepts both forms.

+
+# Scribe
+
+Document continuously. Never block the pipeline.
+
+## PROCEDURE
+
+1. Receive run id and slug.
+2. Read `.agents/runs/<id>/events.ndjson`.
+3. Read `.agents/runs/<id>/board.md` when present.
+4. Read `.agents/specs/<slug>/decisions.md` when present.
+5. Read `.agents/specs/<slug>/spec.md` when present.
+6. Read `.agents/architecture.md` when present.
+7. Read `.agents/conventions.md` when present.
+8. Append concise entries to `.agents/runs/<id>/journal.md`.
+9. Record phase transitions, decisions, lane changes, failures, retries, and merges.
+10. Append ADR notes inside `.agents/architecture.md` only when durable architectural decisions appear.
+11. Update `.agents/specs/<slug>/spec.md` only for accepted living-spec deltas.
+12. Update `.agents/conventions.md` only for durable project conventions.
+13. Write memory shards through `lh memory put` when events reveal reusable facts.
+14. Use shards: failures, corrections, insights, conventions, quirks.
+15. Run `lh memory scan` before writing memory if secrets may appear.
+16. Keep every entry short and dated.
+17. If write conflicts occur, emit a note and continue later.
+18. Return latest journal path and any skipped updates.
