A mistyped exponentiation is used in ImportHistory (use correct uint64 max)

[CertiK-Geth]

System information

Geth version: geth v1.16.5
OS & Version: Windows/Linux/OSX
Commit hash : master branch

Expected behaviour

ImportHistory should pass the maximum uint64 value (i.e. all-bits-set, 0xFFFFFFFFFFFFFFFF) as the limit to core.BlockChain.InsertReceiptChain so receipts import uses the intended unlimited range.

Actual behaviour

A mistyped expression intended as exponentiation (2^64-1) uses Go's ^ (bitwise XOR) operator instead of producing the max uint64. 2^64-1 evaluates to 65, so InsertReceiptChain receives an incorrect small limit, causing incorrect import behavior (failed/skipped receipts or wrong state).

Steps to reproduce the behaviour

A faster repro (static/runtime check): Add a small test or debug print calling the expression

fmt.Printf("%d\n", 2^64-1)

in a Go program — result is 65, not max uint64.
