Add evidence-backed, device-specific non-trace CMSIS-Pack Debug Description sequences to an existing Device Family Pack PDSC. Use for device unlock, debug-port setup, reset, bootloader, flash, debug-authentication, multi-core startup, or reliable debug through sleep, deep-sleep, and device low-power modes after `$debug-access-knowledge` and `$debug-knowledge` have established the required facts; use the shared PDSC preparation, debugvars, application, and XML-validation skills for their respective integration work; do not use for CoreSight trace setup.
