Don't prune variable-depth children while a minzoom-gated feature is pending The minzoom_feature_pending flag from #397 keeps a variable-depth pyramid subdividing until explicit per-feature minzooms are satisfied, but two gaps let features still be dropped: The flag was only set when tippecanoe_minzoom > z + 1, so a feature whose minzoom is exactly z + 1 never marked the tile pending, even though a leaf at z carries only z-visible content. The early-stop commit never consulted the flag: a tile that succeeded in stopping early inserted itself into skip_children_out unconditionally, pruning the children the pending feature needed. The flag only inflated estimated_complexity_out, which the pruning ignores. Set the flag for any feature excluded below its minzoom, include it in the early-stop veto, and skip child pruning while it is set. Adds a fixture covering the minzoom == z + 1 boundary; make test passes with no diffs to existing fixtures.
