Burn half-life set for neuron registration .

From Chain Metadata

Burn half-life set for neuron registration.

Migration Notes

v424 v432 Breaking

netuid changed from u16 to NetUid

Update decoders: SCALE encoding is positional, so any signature change (added, removed, or type-changed fields, or storage shape changes) shifts byte offsets and existing decoders will misparse this item. Re-derive types from the new metadata.
