Lock On: observe "beyond its sight" in the sim's own sensing, pin the hostile's facing, stage off axis, read the lock's Strength

Browse source 
The Update(0) checks could not fail and the 40..200 tick window was tuning. The test now asks the hostile's
PassiveInfo for the player's signature against the detection threshold after the first real tick, asserts the
hostile has no track then, pins the facing, and asserts the Track paint's Strength rises. The hostile is staged at
(1500, 3700) facing the player. The unsound comment about the player's sight is corrected.

Builds: not yet verified (verify job follows).
