Index AMPW's mods: ShaderExtensions, MPFX, KSAGEffects (need KittenExtensions)

[Maximilian-Nesslauer]

Requested by @AMPW-german in the KSA Modding Society #ckan channel on 2026-07-05. All three are on GitHub under AMPW-german, have releases, and require KittenExtensions, so this is gated on KittenExtensions being indexed first (#4).

• ShaderExtensions (MIT, latest v0.2.1): https://github.com/AMPW-german/ShaderExtensions
• MPFX (MIT, latest v0.2.2): https://github.com/AMPW-german/MPFX
• KSAGEffects (GPL-3.0, latest v0.1.6): https://github.com/AMPW-german/KSAGEffects

All three should declare depends on KittenExtensions (and StarMap).

MPFX and KSAGEffects both also depend on ShaderExtensions and MPFX has ModMenu as dependency as well.
