The example enables CONFIG_ESP_SYSTEM_USE_FRAME_POINTER, which pushes the
bootloader to 0x6020 bytes on ESP32-H4. That exceeds the 0x6000 budget
available with the default partition table offset of 0x8000, breaking the
build for both the app_trace_jtag and app_trace_uart CI configurations.
Move the partition table to 0x10000 on ESP32-H4, same as already done for
ESP32-P4, and drop the now stale "only overflowed on P4" note. Tell OpenOCD
the matching app image offset so GDB can map flash on both chips.
Lock take called esp_timer_get_time() before trying the spinlock, and the
C3 default timestamp went through esp_timer's tick-to-us conversion.
Try the lock first, and read systimer ticks directly.
Move 7 trace-related examples (app_trace_basic, app_trace_to_plot,
esp_trace_custom_library, function_tracing, gcov, sysview_tracing,
sysview_tracing_heap_log) from examples/system/ into a dedicated
examples/system/tracing/ subdirectory for better organization.
Update all path references across documentation (en + zh_CN),
build-test-rules, CI configs, Kconfig, and component READMEs.
