- FITCoder: skip record points where lat/lon == Int32.max (FIT invalid sentinel) to prevent coordinate jumps to 180/180 inflating distances
- FITDecoder: use unsigned bitPattern for sint16/sint32 to avoid left-shift overflow on negative semicircles (crashes for southern/western hemisphere)
- FITEncoder: write new definition messages when field layouts change for the same message type
- FITTypes: clamp semicirclesFromDegrees to Int32 range to avoid overflow at 180
- SimpleFITTests: suppress #expect(true) always-passing warning
