skill: add usb-target-debug — device-side capture & debug on the HIL rig
Completes the debugging toolset (usbmon = what the host exchanged,
usb-debug = why the host acted, usb-sniffer = what crossed the wire):
TU_LOG/RTT capture, per-probe GDB autopsy without reset, RAM ring-buffer
event trace, J-Link DWT_PCSR PC-sampling, dual-side capture posture, and
board-lock rig discipline. Includes the implementation plan it executes.
Hard-won warnings baked in from real bring-up sessions: volatile ring
buffers vs -Os dead-store elimination, RTT NO_BLOCK_SKIP post-mortem
limits (no overwrite mode exists), DHCSR validity anchors for register
snapshots, release-lock-before-hil_test, and that a marginal just-recabled
link can fake a deterministic firmware bug.
Also ignore .claude/worktrees/.
