Drew T ef85803b1f feat(phase-29): backlog prune — compact the append-only near-miss log + wire into make report
The near-miss ledger (.run/backlog.jsonl) is append-only, so it filled with already-banked noise:
6,867 rows, ~98% banked. load_best()/render() already filtered on READ (docs/backlog.md was correct),
but the raw log drifted stale and every render re-scanned all 6,867 rows against the stub oracle.

- backlog.py: new `prune` subcommand — atomic rewrite (temp + os.replace) to load_best()'s output
  (drop-now-matched P9 + best-per-addr collapse). Idempotent. 6,867 -> 1,704 open near-misses.
- Makefile: `backlog.py prune` wired into `make report` (BINARY=main block) so the ledger tracks
  reality every cycle instead of drifting.
- Finding (Drew's question): crack waves DO log every non-byte-match to the backlog durably
  (gate_stage copies best_draft -> .run/backlog_drafts/). BUT the `closeness` field is UNRELIABLE —
  byte-correct drafts (match_one MATCH) are logged with closeness>0 (e.g. func_8012F49C logged 29,
  actually MATCH). And a reach-N function's draft is overlay-SPECIFIC (per-location symbols), so the
  backlog is a messy recovery source vs the fresh per-wave stranded drafts. Integration-recovery
  should consume the fresh wave-dir strandeds, not re-derive from the backlog.
