Public function docstrings belong exclusively in .h headers per coding convention. Only static helper functions and static variables retain docstrings in .c files. Removed 413 duplicate docstrings across 185 files (15 CBM + 15 C SDK projects). All 30 projects rebuild with zero errors.

* @brief Repeating timer alarm demonstration.
|
|
*
|
|
* Configures TIMER0 alarm 0 to fire a callback every 1 second.
|
|
* The callback prints "Timer heartbeat" over UART. The main
|
|
* loop idles with WFI.
|
|
*
|
|
* Wiring:
|
|
* GPIO0 -> UART TX (USB-to-UART adapter RX)
|
|
* GPIO1 -> UART RX (USB-to-UART adapter TX)
|
|
* No external components required
