Camera: smooth the walk look-ahead + pull default zoom in (feel)

Browse Source 
The movement look-ahead added its 2.5u lead raw onto the framed point and smoothed only the final camera position, so the lead target snapped with the instantaneous input -- start/stop panned the view and reversing direction swung it ~5u (the jarring walk-shift).

Fix with the genre-standard separate view-position technique: ease a dedicated _leadOffset toward the desired lead via a new gentle LeadSharpness knob, independent of FollowSharpness. Cut the lead magnitude 2.5->1.0 (AimLeadDistance, 0 = fully centred like Diablo/PoE) and pull the default zoom 16->13 (~19% closer). Code defaults + the live Game.unity Main Camera values both updated. See 2026-06-11_Camera_Feel_LookAhead_Zoom.
