- kill_traffic(): stop the recording at --duration-ms exactly, then reap
the workload, instead of waiting on it (up to 60s) before -stop
- sysview_report.py: key open_calls by (func id, context) so interleaved
callers of the same function don't cross-pair CALL/RET
- build.yml: intersect the sysview dep-fetch board list with the PR's own
HIL selection (tinyusb.json vs hfp.json), and skip entirely when HIL is
not running for this PR
- nrf54h20dk: shrink SYSVIEW_BUFFER_SIZE_DEFAULT to 4096 -- .data/.bss sit
in the 32 KiB primary RAM, so the family's 65536 default fails to link
- tusb_sysview.c: copy pcTaskName into a local buffer at snapshot time so
a task deleted mid-lap can't leave SendTaskInfo() dereferencing a freed TCB
- sysview_ci.py: drop a comparison against a baseline whose capture config
(example/workload/duration_s) changed, and fail cdc_burst when the link
stays enumerated but echoes nothing back
- SKILL.md: document the WCH post-mortem dump path (OpenOCD, no J-Link)

The dual-role dogfood measured the 4096 fallback losing 96.7% of ISR exit
contexts on mimxrt1064_evk and 99.1% on metro_m4_express; a local-board run
measured stm32u575nucleo losing ~19% of the whole stream under a 12 s
cdc_msc workload. The default was too small for any real capture on fast
parts and every user had to rediscover that per board.
Families now declare SYSVIEW_BUFFER_SIZE_DEFAULT in family.cmake (the
SYSVIEW_RAM_BASE_DEFAULT pattern): imxrt, nrf, rp2040, samd5x_e5x, stm32f4,
stm32f7, stm32h7 and stm32u5 set 65536, the measured-safe value.
-DSYSVIEW_BUFFER_SIZE still beats everything; small-RAM parts keep the 4096
fallback and their per-board overrides (stm32f072disco's 2048 verified
still honoured). lpc55 measured 34 lost events on the same route, an order
of magnitude lighter, so it keeps the fallback rather than inheriting a
default on thin evidence.

hw/bsp/sysview_freertos_hooks.h maps the FreeRTOS trace macros onto
SystemView task records (task names, switches, ready/blocked) and adds heap
tracking; the FreeRTOSConfig.h of the families used on the rig include it
when SYSVIEW is on.
The FreeRTOS examples grow their USB task stacks when CFG_TU*_SYSVIEW is
enabled, the same way they already do for CFG_TUSB_DEBUG -- the
instrumentation's stack cost is real (measured overflows on lpc55 before
the bump).

nrf52840dk: 16 MHz TRACECLK (hardware cap) width 4, P25 soldered, SW7=Alt;
no family code needed (J-Link arms TRACECONFIG). nrf5340dk: TRACE_ETM
builds force the TAD port to 16 MHz (SystemInit's 64 MHz is marginal),
+3 ns sample timing; the interface MCU's UART1 flow control drives the
trace pins - SB27/SB28 must be cut (P0.10/P0.11 = TRACEDATA1/0).

add board_uart_read() for nrf

IAR is only supported with CMake. Remove all IAR-specific references
from the Make build system including toolchain files, SRC_S_IAR,
LD_FILE_IAR variables, and IAR toolchain detection.
Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and
broken formatting in stm32f7 board_uart_write.
