Fix wheel_pattern regex to support negative Count and Deg values

[Copilot]

The wheel_pattern regex in _reconstruct_encoder_from_logger failed to match wheel events with negative Count or Deg values, silently dropping those encoder readings.

Changes

• Count group: (\d+) → (-?\d+) to handle negative integer counts
• Deg group: ([0-9eE+\.-]+) → ([-+\d\.eE]+) to explicitly handle negative degrees and preserve ± sign support in scientific notation

# Before
wheel_pattern = re.compile(r'^Wheel-Index-(\d+)-Count-(\d+)-Deg-([0-9eE+\.-]+)$')

# After
wheel_pattern = re.compile(
    r'^Wheel-Index-(\d+)-Count-(-?\d+)-Deg-([-+\d\.eE]+)$'
)
