Migrate to TypeScript 7.0.2

[tom2drum]

Description and Related Issue(s)

Upgrade the project to TypeScript 7.0.2 (native Go compiler) for faster type-checking in CI and local development.

Proposed Changes

• Add @typescript/native (typescript@7.0.2) as the compiler used by tsc / pnpm lint:tsc.
• Alias typescript to @typescript/typescript6@6.0.2 so typescript-eslint and other tools that rely on the TS 6 programmatic API keep working until TypeScript 7.1 ships a new API.
• Bump workspace sub-packages (deploy/tools/*, @blockscout/ui-toolkit) from TypeScript 6.0.3 to 7.0.2.
• Exclude node_modules_linux from the ui-toolkit tsconfig (local Docker artifact that TS 7 was type-checking due to the broad rootDir).

Breaking or Incompatible Changes

None for application code. Type-checking behavior should match TypeScript 6.0 with stableTypeOrdering enabled (TS 7 default).

Additional Information

Side-by-side setup: node_modules/.bin/tsc → TypeScript 7.0.2; node_modules/.bin/tsc6 → TypeScript 6.0.2 (ESLint).

Release-age policy: TypeScript 7.0.2 packages were published on Jul 8, 2026 and clear the 1-week minimumReleaseAge on ~Jul 15, 2026. This PR intentionally does not add minimumReleaseAgeExclude entries — CI pnpm install may fail until then. Plan: mark ready for review on Wednesday when packages are mature enough.

Editor: For the faster language server, enable the TypeScript 7 extension in VS Code/Cursor ("Enable TypeScript 7 Language Server").
