Off-board state flag correction

The user reported jumps immediately playing a landing animation, repeated landing animations and rising motion after walking off a ledge. The preceding run's stderr contained no airborne bail report; this alone does not establish whether the airborne state was entered.

Static evidence: TU3 dump default_82000000_011B0000.bin, SHA-256 f4aa113eb541bfba03dbc108cf5ab43f58c965b20fa3b82f9c40938a0ad841c4. The generated instruction listing for 82D8ADE8 contains:

• 82D8B8D4: lhz r11,2484(r4), followed by a low-bit test.
• 82D8B490 and 82D8B5F0: lbz r11,2484(r4), followed by a low-bit test.

On this big-endian target these test full-word masks 0x00010000 and 0x01000000, respectively. The port incorrectly used 0x00000001 for all three. Bit16 is published from Offboard328, the airborne continuation flag; bit0 is a separate animation attribute. BipedAir therefore incorrectly returned to BipedGround while its airborne flag was still set.

Corrected all three masks. Repeated premature ground entry is a plausible cause of the reported animation loop; gameplay confirmation remains with the user. Build only, no tests run. Bounded bail diagnostics also cover BipedGround so any remaining turning-related failure can be captured.
