x3b/§13.10: productionise leaf-sharing — per-code share grain + CLI wiring

Make the §13.3 lever a first-class feature, not experiment-only.

- programme.py: SpaceReq.share (default 1) + has_share, parsed from
  patterns.config 'share: N'.
- operators._share_grain: resolve per-code grain from leaf_share_factor
  selector — 0 = per-code opt-in (share iff share:N>=2), >=2 = global with
  per-code override (share:1 opts OUT, share:N sets grain). _share_rooms
  groups per resolved grain.
- End-to-end conf injection without monkeypatch: load_config(overrides=)
  merges run-level keys last; driver.search / innerloop.optimise /
  NativeEvaluator / _fitness_for thread conf_overrides={leaf_sharing:True}
  through both inner-loop and off-tree scorers when sharing is on.
- homemaker-evolve: --leaf-sharing/--no-leaf-sharing + --leaf-share-factor
  (env HOMEMAKER_LEAF_SHARING / HOMEMAKER_LEAF_SHARE_FACTOR).
- Example programmes untouched (§13.3/§13.9 stay reproducible). Experiment
  load_config monkeypatches updated to accept overrides=.

Tests: grain modes, opt-out, default-OFF parity, load_config overrides,
programme parse, CLI parse. 233 pass. Smoke: harbor 37 vs 95 fails on/off.

erc.7d/§13.7: high-budget harbor floor probe — close 71d NO-GO, wrap Phase 8

500k serial full-stack harbor probe (probe_harbor_floor.py): 20 fails,
crinkliness 13→4, landlocked crinkliness ~13→2 of 20. Interior-O (default-ON,
erc.8) is 71d's named fix and dissolved its landlocked-crinkliness target;
residual now diffuse (top class edge-too-long). NO-GO on 71d.

Cumulative Phase-8 floor vs §12.2 baseline (leaf-share-relaxed): maple
136.0→80.3 (−41%), harbor 74.0→34.0 (−54%) — all from construction levers,
none from search machinery, per the epic thesis.

Closes erc epic: 71d/7u5/jrb/u8x superseded-by-construction; erc.5/erc.6
wont-fix (Diag A/B revisit conditions unmet). DESIGN §13.7.
