"Add stake and burn" event: alpha token was purchased and burned.
Migration Notes
v424 v432 Breaking
netuid changed from u16 to NetUid; amount changed from u64 to TaoBalance; alpha changed from u64 to AlphaBalance
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.
