- Added precise fractional mouse wheel delta handling with per-step command emission. - Introduced scroll accumulators (`wheel_accum_y_`, `wheel_accum_x_`) for high-resolution trackpad input. - Replaced hardcoded ESC delay with configurable `kEscDelayMs` constant in `TerminalFrontend`. - Enabled mouse position reporting and reduced CPU usage during idle with optimized `timeout()` setting.
