chore(docs): remove orphaned shader checks

[vercel-gh-bot-2]

Summary

rg finds no tracked callers for the two shader check scripts. The docs package does not register them in a package script, Vitest only includes lib/**/*.test.ts, and the paint check exits with ERR_PACKAGE_PATH_NOT_EXPORTED on current main.

Because neither the build nor test graph executes these files, deleting them should remove 188 lines of stale test-like code without changing renderer behavior or automated coverage.

package scripts / CI / Vitest   no edge   shader check scripts
docs renderer                   imports   shader runtime modules (unchanged)

Before this change, TypeScript parsed both scripts but nothing ran them. After this change, the orphaned entry points are gone. The renderer and its runtime imports are unchanged.

Validation

• pnpm --filter eve-docs test:unit (21 files, 136 tests passed)
• pnpm --filter eve-docs exec next typegen && pnpm --filter eve-docs exec tsc --noEmit
• pnpm lint
• pnpm guard:invariants
• pnpm docs:check
• pnpm exec oxfmt --check apps/docs
• git diff --check

pnpm typecheck remains blocked in the unchanged agent-tui-client fixture because its configured compaction model lacks AI Gateway context-window metadata.

Checklist

• I linked an issue with prior discussion confirming this change is wanted
• I ran the relevant checks from CONTRIBUTING.md
• I added tests and documentation where relevant
• I added a changeset if this touches the published eve package
• DCO sign-off passes for every commit (git commit --signoff)
