Louder Ambience (was very quiet before)

Fixed:

Resolved map flickering issues caused by older optimization techniques on Valve official maps (e.g., Half-Life 2, CSS) and potentially on other maps. The flickering was triggered by dynamic visibility systems like area portals and culling mechanisms.

Changes:

Added default execution of the following commands to disable certain optimizations:
r_3dsky 1: Ensures 3D skyboxes are always rendered, improving outdoor visuals.
r_portalsopenall 1: Disables area portal optimizations to prevent visibility recalculations and rendering glitches.
These changes ensure smoother operation of the addon and reduce visual artifacts.
