hathach 21bbcb5bbf docs(target-debug): vector catch, SWO trace, verifybin, FreeRTOS threads; table integration
- Vector catch + Cortex-M fault autopsy, verified with a deliberate bad-load
  on stm32f407disco: CFSR=0x8200 (BFARVALID|PRECISERR), BFAR = exact bad
  address, stacked pc addr2lined to the faulting line; gotchas recorded
  (stale FPB comparators fire phantom SIGTRAPs — scrub first; arm DEMCR
  after reset; loads precise / stores imprecise; ARMv6-M has no CFSR/BFAR)
- SWO exception trace + hw PC sampling gate PASSED on F407: 680 KB of
  packets in 3 s (0x17 PC samples in flash range, 0x0E SysTick enter/exit);
  JLinkSWOViewerCL decodes stimulus only — raw SWORead is the recipe;
  SWOStart needs an explicit speed headless
- verifybin 'Verify successful.'; FreeRTOS -rtos plugin lists all 6
  cdc_msc_freertos tasks after a run->stop cycle (plain attach = 0xDEAD
  placeholder); semihosting anti-note; monitor-mode pointer (untested)
- Intrusiveness table gains the new rows; agent playbook bullet updated;
  retrieval gate 5/5 with a fresh reader; executed plan committed
