DelayLineStreamPacer

Fixed-delay pacer — gate on a configurable millisecond wait.

Declared in src/libs/libserialsession/serialsession/DelayLineStreamPacer.hpp.

Detailed description

After each line is written, arms a single-shot timer for config.delayMs; on expiry, emits requestNextLine. With a clock set (LineStreamPacer::setClock), it records the deadline instead, and poll() emits requestNextLine once the clock reaches it.
