Applied the standard MIT license header to all project-owned C, header,
assembly, shell, and Python files that were missing a copyright notice.
Third-party, toolchain startup, and auto-generated files were excluded.

* Fixed race condition and message loss in Cortex-M GNU, AC6, and IAR ports (#516)
- Added compiler memory barriers to BASEPRI management functions in tx_port.h.
- Added architectural barriers (DSB/ISB) to scheduler return paths in tx_port.h and tx_thread_system_return.S to prevent fall-through before context switch.
- These changes address spurious thread resumption and lost messages, especially when TX_NOT_INTERRUPTABLE is enabled.
- These changes ensure that pending interrupts (specifically PendSV) are recognised before subsequent instructions are executed, following Kairalite's feedback and ARM architectural guidelines.

* Added a comment in common/tx_queue_cleanup to document why the NI path omits revalidation guards
- In `TX_NOT_INTERRUPTABLE` mode, the caller keeps interrupts disabled across the entire cleanup call, so the race window that makes the guards necessary in the interruptable path cannot occur. Add a comment explaining this, and noting that all paths that resume a suspended thread clear tx_thread_suspend_cleanup before calling
_tx_thread_system_ni_resume, making double-cleanup impossible.
This prevents future false-positive suggestions (e.g. from AI tools) to add redundant checks to the NI path.

Problem with first system tick was detected, it needs much more time for the first tick as it's defined. The reason for this behavior is incorrect initialization of the SysTick timer in the port file for the Cortex-M0. It doesn't reset the SysTick Current Value Register despite the fact that its value is not initialized at startup (see https://developer.arm.com/documentation/dui0552/a/cortex-m3-peripherals/system-timer--systick). So if we have 0xFFFFFF (this register has 24-bit), it means we will get about 256*256*256 / 48000000 for the tact frequency of 48MHz to reach the zero, that makes 350ms delay at startup.
