Soleron 1.1

- Added Minecraft Java Edition 26.2 / current Iris compatibility maintenance.
- Added an explicit gbuffers_textured_lit fallback for lit particles and related geometry.
- Added an explicit final passthrough stage.
- Fixed a lens flare strength typo (6.040 -> 0.040).
- Fixed the nighttime post-process tint using an unintended green-heavy blue value.
- Fixed excessive distance fade brightening caused by an out-of-range mix factor.
- Made depth-edge sampling safe at screen borders and during viewport resize/reload.
- Added projection division safety for sun/moon screen projection.
- Simplified gbuffers_basic so line/basic geometry no longer depends on lightmap UVs.
- Limited the shadow sample setting to the 32 Poisson samples the shader actually provides.
- Removed dead/invalid settings slider entries.
- Minor naming and metadata cleanup.
- Preserved the original Soleron lighting, bloom, shadows, god rays and overall visual style.
