Device Monitor Core Architecture & Memory Statistics

[AmmarOkla12772]

Implement the foundation of the NUCLEO_F401RE Device Monitor Demo. Introduce a Monitor/Reporter thread architecture and migrate thread stack allocation to a ThreadX byte pool to enable runtime memory diagnostics.

Goals:

• Create a global TX_BYTE_POOL for dynamic allocations.
• Allocate thread stacks from the byte pool.
• Add a Monitor Thread to collect:
• System uptime (tx_time_get)
• Byte pool statistics (tx_byte_pool_info_get)
• Add a Reporter Thread to periodically display diagnostics over USART2.
• Retain heartbeat and worker threads for scheduler activity.

DoD:

• Device boots successfully on hardware.
• UART output updates every 2 seconds.
• Uptime increments correctly.
• Memory statistics remain stable during extended execution.
• System runs continuously for at least 5 minutes without lockups.
