fix(link-daintree): correct family-gate fallback in fan-out import (#153)

When inferring a family from preset env (e.g. ANTHROPIC_* → "anthropic"),
the findVanilla() pool construction erroneously returned [] instead of all
candidates when no vanilla slot matched the inferred family.

Fix: change pool construction from:
  familyMatch.length ? familyMatch : (family ? [] : candidates)
to:
  familyMatch.length ? familyMatch : candidates

The family gate is still respected when matches exist; when it doesn't,
we correctly fall back to all candidates sorted by daintree_preset_id
then numeric suffix.

+- fix(link-daintree): fan-out fallback logic no longer silently drops presets when no vanilla provider has a matching `provider` field — the family gate is now correctly bypassed when the inferred family doesn't match any vanilla slot, falling back to all candidates sorted by daintree_preset_id then numeric suffix
