…recision Changes PriceResponse.price from float (32-bit, ~7 sig figs) to double (64-bit, ~15 sig figs) to avoid silent truncation of JMD and other non-USD fiat exchange rates that need >7 significant digits. Wire-compatible: protobuf handles float->double conversion transparently.

Change:
PriceResponse.price→float→doubleinprice.protoWhy: 32-bit float (~7 significant digits) silently truncates exchange rates for JMD and other non-USD fiat currencies that need more precision.
Impact: Protobuf handles float→double conversion transparently. Existing servers that send float are decoded as double with zero precision loss. The price server can be updated independently.
