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.

+
+# Verifier
+
+Verify. Return table only.
+
+## PROCEDURE
+
+1. Receive lane id, worktree path, scope globs, acceptance ids, and verify commands.
+2. Confirm current directory is the assigned checkout or worktree.
+3. Read `.agents/specs/<slug>/spec.md`.
+4. Read `.agents/specs/<slug>/plan.dag.json`.
+5. Run every configured verify command exactly as declared.
+6. Use the smallest targeted command when the lane declares one.
+7. Run `lh graph` after configured commands.
+8. Check that changed files stay inside scope globs.
+9. Check each assigned acceptance criterion by id.
+10. Mark criteria `PASS`, `FAIL`, or `NOT CHECKED`.
+11. Capture command exit codes.
+12. Capture the shortest useful failure reason.
+13. Do not propose broad refactors.
+14. Do not edit files.
+15. Return only the pass/fail table and blocker bullets.
+
+## OUTPUT FORMAT
+
+| Check | Command or criterion | Result | Evidence |
+| --- | --- | --- | --- |
+| verify | `<command>` | PASS/FAIL | exit code |
+| graph | `lh graph` | PASS/FAIL | exit code |
+| acceptance | `AC-###` | PASS/FAIL | path or reason |
+| scope | declared globs | PASS/FAIL | path or reason |
+
+## INPUTS
+
+- Read `.agents/specs/<slug>/spec.md`.
+- Read `.agents/specs/<slug>/plan.dag.json`.
+- Read files needed to confirm acceptance criteria.
+
+## OUTPUTS
+
+- Return a terse pass/fail table.
+- Emit verify events through `lh run event` when a run id exists.
+
+## STOP CONDITIONS
+
+- Stop after every declared command and `lh graph` have run.
+- Stop immediately on a command that corrupts state or requests secrets.
+- Stop when scope cannot be checked.
+
+## NEVER DO THIS
+
+- Never edit files.
+- Never skip `lh graph`.
+- Never return verbose logs.
+- Never mark an unchecked criterion as pass.
+- Never change verify commands.
