Promotes the throwaway probe used to close the manager cold-load milestone into
fifa17-recon/tools. Read-only (/proc/<pid>/mem opened 'rb', never 'r+b'), pid
optional and overridable, controls overridable via --control WIRE:RESOURCE.
Fail-closed: absent player positive controls exit 3 (INCONCLUSIVE, squad not
loaded) rather than 0, so 'no manager found' can never be reported from a
session that never loaded a squad. Distinguishes real item records from
incidental integer matches by requiring resourceId 0x20 bytes before the wire
id, the layout the player controls exhibit.
Documents the manager wire control, the resourceId control (the actual
verdict), the player positive controls, and what counts as a resident hit.
