fix(ci): resolve broken job name in shader validation workflow

[doodlum]

Summary

• Removed the single-entry matrix strategy from the shader-validation job in _shared-build.yaml
• Inlined the "Flatrim" name and config file path directly into the job

Why

When the shader-validation job is skipped (because inputs.run-shader-validation is false), GitHub Actions doesn't expand matrix expressions — causing the job name to display as the raw literal ${{ matrix.config.name }} in the UI. Since the matrix only ever had one entry, removing it and inlining the values fixes the display without changing behavior.

Test plan

• Verify the job name shows "Validate shader compilation (Flatrim)" in the PR checks UI
• Confirm shader validation still runs correctly when triggered

📝 Walkthrough

Walkthrough

The shader-validation job in the shared build workflow is simplified from a matrix-based configuration that iterated over multiple validation configs to a single fixed validation run. The job header, cache key suffix, hardcoded config file path, and artifact naming are all updated to remove matrix dependencies.

Changes

Shader Validation Job Simplification

Layer / File(s)	Summary
Shader validation job hardwiring .github/workflows/_shared-build.yaml	The shader-validation job removes its matrix strategy and converts all matrix-derived values (job naming, cache suffix, config file selection, artifact naming) to fixed hardcoded values, reducing the job from dynamic multi-config iteration to a single static validation run.

Poem

🐰 No more matrices to spin and dance,
One shader path gets its steady stance,
Cache keys simple, config now fixed,
Artifacts unified, no longer mixed!
The workflow hops forward, sleek and lean. ✨
