chore: drop vite-plugin-checker and tidy vite config types

[kaladinlight]

Description

• Remove vite-plugin-checker from the dev pipeline (and dependency). It was the dominant local dev perf bottleneck; CI and editor LSP already surface TypeScript errors.
• Type publicFilesEnvVars as Record<string, string> so the dynamic VITE_SRI_* / VITE_CID_* keys built from the public/ directory type-check.
• Suppress multiformats/cid|codecs/raw|hashes/sha2 imports with @ts-expect-error. multiformats v9 ships types but excludes them from its package exports, so TS can't resolve them. The package is only used at build time for SRI/CID computation, so suppressing inline is cleaner than declaring ambient modules.

Issue (if applicable)

Risk

Build/dev tooling only; no runtime app code changes. Dev type errors will no longer block via overlay — they still surface in editor and CI.

What protocols, transaction types, wallets or contract interactions might be affected by this PR?

None.

Testing

Engineering

• pnpm install then pnpm dev — confirm dev server starts and is noticeably faster on cold/warm boot
• pnpm build — confirm production build still succeeds and emits SRI/CID env vars correctly
• pnpm type-check — confirm no new TS errors

Operations

• 🏁 My feature is behind a flag and doesn't require operations testing (yet)

📝 Walkthrough

Walkthrough

The PR removes the vite-plugin-checker development dependency and its integration from the Vite configuration. Additional refactoring adjusts async plugin hooks to synchronous, adds TypeScript suppression annotations for type-less imports, refines type constraints, and reformats build optimization expressions.

Changes

Cohort / File(s)	Summary
Dependency Cleanup package.json	Removes vite-plugin-checker from devDependencies.
Vite Configuration Refactoring vite.config.mts	Removes vite-plugin-checker plugin integration and import. Changes two custom resolveId hooks (ethers v5 and bech32 v1) from async to synchronous. Adds TypeScript suppression comments for untyped multiformats imports. Constrains publicFilesEnvVars type to Record<string, string>. Reformats alias paths and manual chunk expressions for consistency.
