Port vanity generator to Solana + Solana branding

[HODL-Community]

Summary

• Ported the generator from Ethereum/secp256k1 to Solana/ed25519 with Base58 prefix/suffix matching.
• Kept the same web UI structure while updating copy and behavior for wallet/program ID targets.
• Added Solana GPU support via a hybrid backend: CPU workers generate keypairs, WebGPU compute shader performs parallel Base58 vanity matching.
• Added full-scale app readiness tooling: unit tests, browser E2E tests, quality scripts, and CI workflow.
• Updated theme + iconography to Solana colors/glyphs and refreshed OG/Twitter/favicons.
• Removed obsolete Ethereum-specific codepaths for maintainability.

Functional Changes

• src/worker/vanityWorker.ts
  • Added generate mode to emit raw Solana key batches (privKeys, pubKeys).
  • Retained CPU search mode as a fallback path.
• src/worker/pool.ts
  • Added generate(batchSize) API alongside search(...).
  • Extended worker message routing for both result types.
• src/webgpu/base58Matcher.wgsl
  • New compute shader for Base58 encoding + prefix/suffix matching in parallel.
• src/webgpu/gpuMatcher.ts
  • New WebGPU matcher runtime (pipeline, buffers, dispatch, match index readback).
• src/ui/app.ts
  • Added backend auto-benchmark/caching (GPU vs CPU).
  • Added GPU runtime path: workers generate keypairs, GPU finds matching index, then app resolves address/private key.
  • Added VITE_FORCE_BACKEND=cpu|gpu support for deterministic testing/troubleshooting.

Full-Scale Test/Prep Additions

• vitest unit test setup:
  • vitest.config.ts
  • tests/unit/solanaAddress.test.ts
  • tests/unit/keys.test.ts
• @playwright/test browser E2E setup:
  • playwright.config.ts
  • tests/e2e/app.spec.ts
  • Headless Chromium flow validates render/validation and real generate→match→reveal flow.
• CI workflow:
  • .github/workflows/ci.yml
  • Runs build, test:unit, installs Chromium, then runs test:e2e.
  • Uploads Playwright artifacts.
• Package scripts:
  • Added typecheck, test:unit, test:e2e, test, check.

UI/Branding

• Solana palette in src/style.css.
• Solana glyph in app header and public/favicon.svg.
• Open Graph/Twitter cards replaced with Solana assets (public/og-image.svg, public/twitter-card.svg).
• SEO/manifest/sitemap/robots updated for vanity-sol-gpu naming.

Cleanup

• Removed Ethereum-only modules:
  • src/wallet/ethAddress.ts
  • src/wallet/keystoreV3.ts
  • src/worker/wasmPool.ts
  • src/worker/wasmVanityWorker.ts
  • src/webgpu/* (old secp256k1 shader path)
• Simplified dependencies/config to Solana runtime needs and re-added WebGPU typings for the new matcher path.

Validation

• npm run build passes.
• npm run test:unit passes.
• npm run test:e2e passes.
• npm run check passes.

Notes

• Mistakes log updated in notes/mistakes.md per repo instruction.
