Capture triage: parse-only census of every wire capture

capture_triage.py parses each capture's first slice (no emulation) and reports the embedded firmware build, action census, init config, and any actions outside cap7's known-good set. Results: all captures share build 0x31440 + the same init config; ravtest (RAV = the walled terrain map), dtest, cap6/cap8/capture/ sharksval are clean cap7-profile candidates; sdemo/duane/fishspls add morph; bt3/munga7 add act31/43/45/list_remove. cap6's earlier "boot derail" was likely just an under-budgeted run (87K cmds to parse), not a fault.
