chore: migrate type-check from tsc to tsgo across all workspaces

[lyzno1]

Summary

Switch every workspace's type-check script from tsc to tsgo (the TypeScript 7.0 beta native compiler from @typescript/native-preview), and drop the transitional type-check:tsgo alias.

On the web workspace alone, pnpm type-check goes from ~54s to ~6s. Running all five workspaces via pnpm type-check (i.e. vp run -r type-check) now finishes in ~7s total.

What changed

• Replace tsc with tsgo in web / e2e / sdks/nodejs-client / packages/dify-ui / packages/migrate-no-unchecked-indexed-access package.json scripts
• Switch the migrate codemod's runtime subprocess (pnpm exec tsc ... → pnpm exec tsgo ...) — all required flags (--noEmit, --pretty, --incremental, --tsBuildInfoFile, --project) are supported by tsgo
• Add @typescript/native-preview to every workspace that runs tsgo so the binary resolves without relying on hoisting
• Pin @typescript-eslint/eslint-plugin to 8.59.0 so it matches the already-bumped @typescript-eslint/parser@8.59.0 (they are released in lockstep, eslint-plugin@8.59.0 has peerDependencies["@typescript-eslint/parser"]: ^8.59.0)
• Add explicit include / exclude to packages/dify-ui/tsconfig.json so tsgo does not scan the generated storybook-static/ JS artifacts (TS 7 is stricter about JSDoc/Closure-style JS than TS 6)
• Drop stale pnpm type-check:tsgo references in AGENTS.md, .agents/skills/**, web/docs/lint.md, web/scripts/refactor-component.js and packages/dify-ui/README.md

The typescript package itself stays as devDep: typescript-eslint, tsslint, knip, Next, vite-plus, and the migrate codemod all import the TS 6 programmatic API at runtime (stable TS 7 programmatic API is planned for 7.1).

Test plan

• pnpm install --frozen-lockfile — clean
• pnpm type-check — all 5 workspaces pass, 0 errors, ~7s total
• pnpm --filter dify-web exec eslint app/layout.tsx — 0 errors (typescript-eslint 8.59.0 / 8.59.0 aligned)
• pnpm --filter dify-client exec eslint src/index.ts — 0 errors
• CI: Web type check step (vp run type-check in .github/workflows/style.yml)
