Detailed Description

Production-grade wrapper around ThreadX Semaphore to mimic std::condition_variable.

• Uses a Counting Semaphore (initialized to 0).
• ISR-safe notification logic (tx_semaphore_put).
• Robust tick overflow handling using elapsed time subtraction.

Note

Limitation: Unlike std::cv, a semaphore retains its signal state. If notify() occurs before wait(), the wait will effectively "fall through".
