bb9b355f14 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.

dba85094ea hph: dissect §13.7 edge-too-long — leaf-sharing artifact + narrow sliver
experiments/diag_edge_too_long.py: the 6 harbor edge-too-long fails are 2
locations — a share=3 combined leaf (247 m², aspect 1.2; flat 8 m cap not
share-aware, unlike quality_size's k×target) accounting for ~4, and one
1.2×16.7 m narrow sliver (~2, also caught by width/proportion). No corridors.
Files homemaker-py-hph (share-aware edge-too-long fix).
