Release FirmMux v1.0.4-beta8 · nextcode4u/FirmMux

TL;DR

This release focuses on UI/theme stability, safer theme asset rendering, and cleanup of several long-running visual regressions.
Theme fonts were removed. Sorry to anyone using custom font-based themes, but the layout drift and per-theme text metric mismatches were causing too many alignment and clipping problems. Stability and consistent UI behavior were prioritized here.
Theme-controlled line spacing, list item height, status bar height, and background visibility were also removed as live layout controls. Older theme keys remain safe and are ignored.
Theme image asset support has been restored with a safer texture upload path. That includes wallpapers, row textures, preview frames, help strips, and status strips.
RetroArch cover previews remain at readable 92x92 sizing with the corrected upload behavior that fixed the old clipped/cutoff preview issue.

Fixed clipped 92x92 cover previews while keeping them readable.
Added date display to the status bar.
Fixed NDS title-data wrapping/newline overlap.
Fixed row text vertical alignment for tabs and lists.
Simplified theme opacity behavior so background visibility no longer globally washes out the UI.
Backgrounds now render at full opacity.
Added per-element alpha controls for theme tuning.
Restored theme asset support and documented the supported asset keys, formats, and recommended sizes.
Added a repo-side themes/test_assets reference theme for asset testing.
Fixed theme debug menu toggle selection.
Switched RetroArch source maintenance to the tracked fork workflow.
