Fhenix Encrypted Bitwise Operations

Overview

Logic (and, or, xor, not) works on ebool | euint8 | euint16 | euint32 | euint64 | euint128.
Shift / rotate (shl, shr, rol, ror) works on euint8…128 only.

Function	Meaning
`and` / `or` / `xor`	bitwise AND / OR / XOR (also on `ebool`)
`not`	bitwise NOT (also on `ebool`)
`shl` / `shr`	shift left / right
`rol` / `ror`	rotate left / right

euint32 masked  = FHE.and(value, FHE.asEuint32(255)); // low byte
euint32 shifted = FHE.shl(masked, 4);                 // << 4
ebool   toggled = FHE.not(flag);                      // ebool also supported
