Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

what do people usually do to separate/abstract platform dependent codes/files
Here is the port - https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/main/portable/ThirdParty/GCC/Posix

TI CC2630: Having trouble deciding Contiki vs TI-RTOS
Freertos has support for generic cortex m3: https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/main/portable/GCC/ARM_CM3 It could very well work almost out of the box with your mcu.

Ted Ts'o: "As an OS engineer, I deeply despise these optimization tricks, since I personally I care about correctness and not corrupting user data far more than I care about execution speed"
the only OS written in iso c i found was RTOS and they have open bug reports due to strict aliasing in simple things like their linked list implementation, which they don't bother to fix because somehow that causes even more problems (?!): https://github.com/FreeRTOS/FreeRTOS-Kernel/pull/54

Arduino or full featured RTOS?
You likely put the requirements of POSIX just to have an excuse. Fyi, FreeRTOS kernel, the only thing you need, is here: https://github.com/FreeRTOS/FreeRTOS-Kernel/

Nutshell custom memory allocators for me
FreeRTOS comes with 5 quite simple reference implementations of the heap memory allocator. You can study how it works.

Using FreeRTOS and dual core RP2040
The main branch is single-core. You're looking for the SMP branch.

C programmers scare me
On non-POSIX systems, malloc & free are implemented differently. EG FreeRTOS has some very simple malloc (and optionally free) implementations, eg heap_2.c (has malloc & free, but doesn't consolidate blocks), or heap_4.c (more complex, tries to prevent fragmentation by consolidating blocks, still less optmized & simpler than the glibc malloc/free used by most Linux systems).

Toit – A Language Designed for Microcontrollers
As long as Toit is licensed under the GNU Lesser General Public License v2.1, I am unlikely to consider using it. By contrast, MicroPython is licensed under the MIT License (MIT).
As others have noted, Toit seems like a bad name. I suppose non-French speakers will tend to inadvertently mispronounce Toit.
Getting traction is hard. In my opinion, having a restrictive license and a bad name make it less likely Toit will gain traction. Finally, Toit licensing reminds me of Mongoose OS https://github.com/cesanta/mongoose-os#mongoose-os---an-iot-....
