Introduces test_dissolve_network_no_storage_leak which automatically detects per-subnet storage that is not cleaned up when a subnet is dissolved. The test: 1. Snapshots ALL raw storage keys before subnet creation 2. Creates a subnet, registers neurons, stakes, serves axon/prometheus, sets childkeys, sets weights, and runs 2 epochs 3. Dissolves the subnet via root 4. Snapshots ALL storage keys after dissolution 5. Diffs the snapshots, filtering to SubtensorModule and Swap pallets, excluding known global storage items This is future-proof: when a developer adds a new per-netuid StorageMap but forgets cleanup in remove_network, this test fails automatically with a clear error message naming the leaked storage item. Also fixes Swap::ScrapReservoirTao and Swap::ScrapReservoirAlpha not being cleaned up in do_clear_protocol_liquidity. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

This test is future-proof: when a developer adds a new per-netuid
StorageMapbut forgets to clean it up inremove_network, this test fails automatically with a clear error message naming the leaked storage item — no need to update the test itself.Test plan
