build: run typechecks with native TypeScript 7

[amondnet]

Summary

• install native TypeScript 7 under the @typescript/native alias so Bun links direct tsc invocations to the faster native compiler
• retain TypeScript 6 as the typescript package for API consumers such as typescript-eslint
• verify in CI that the selected tsc binary remains TypeScript 7

Motivation

TypeScript 7 provides substantially faster native compilation, but it does not expose the JavaScript compiler API required by typescript-eslint. The TypeScript team recommends running TypeScript 6 and 7 side-by-side during this transition:

• TypeScript 7.0: Running Side-by-Side with TypeScript 6.0
• typescript-eslint #10940 tracks native TypeScript support and is blocked on a stable API
• typescript-eslint #12518 directs TypeScript 7 users to the side-by-side approach

The documented @typescript/typescript6 alias layout currently resolves circularly under Bun 1.3.14. This PR uses the Bun-compatible equivalent: normal typescript@^6.0 for imports and @typescript/native as an alias to typescript@^7.0.2 for the tsc binary.

Verification

• bun install --frozen-lockfile
• bun run lint
• bun run check:typescript-version → Version 7.0.2
• bun run typecheck --force → 9 successful tasks, 0 cached
• direct tsc workspaces (worker, core, CLI, and create-statusbeam) each resolve Version 7.0.2
• the CI guard predicate rejects Version 6.0.3 with a non-zero exit code

Caveats

• Editor language services continue to use TypeScript 6 because TypeScript 7 does not provide the legacy tsserver API.
• Astro checks are not accelerated: the docs workspace retains TypeScript 5.9, and Astro's checker currently supports TypeScript 5/6.
• Dependabot may not automatically update the aliased @typescript/native dependency.
• Remove the alias and compatibility guard once typescript-eslint supports the TypeScript 7.1 API.
• If the dependency lockfile changes before merge, this branch may need a trivial bun.lock rebase.

Summary by cubic

Run typechecks with the native TypeScript 7 compiler for faster tsc, while keeping typescript@^6 for tools that use the JS API like typescript-eslint. Adds the @typescript/native alias to typescript@^7.0.2 and a CI check (bun run check:typescript-version) to ensure tsc stays on 7.x.

Code Review

This pull request adds the @typescript/native dependency and introduces a check:typescript-version script to package.json. The reviewer feedback correctly identifies a portability issue with using grep on Windows environments and suggests a cross-platform Bun one-liner to verify the TypeScript version instead.

[MEDIUM] Non-portable grep command in package.json script

Problem: The check:typescript-version script uses grep, which is not natively available on Windows environments, leading to potential failures for Windows contributors.
Rationale: To ensure cross-platform compatibility and a consistent developer experience, scripts in package.json should avoid platform-specific shell utilities like grep.
Suggestion: Use a cross-platform Bun/Node.js one-liner to verify the TypeScript version.

Suggested change

	"check:typescript-version": "tsc --version | grep -E '^Version 7\\.'"
	"check:typescript-version": "bun -e \"if (!require('child_process').execSync('tsc --version').toString().startsWith('Version 7.')) process.exit(1)\""

Greptile Summary

Adds a side-by-side TypeScript toolchain that preserves TypeScript 6 for JavaScript API consumers while selecting the native TypeScript 7 compiler for direct tsc invocations.

• Adds the aliased @typescript/native dependency and locks its platform-specific binaries.
• Adds a script that verifies the selected compiler reports TypeScript 7.
• Runs the compiler-version guard in CI before workspace typechecking.

Confidence Score: 5/5

The PR appears safe to merge with no concrete blocking or independently actionable issues identified.

The dependency layout preserves TypeScript 6 under its normal package name, exposes TypeScript 7 through the alias for direct compiler invocations, and adds a CI guard to detect incorrect binary selection.

Important Files Changed

Filename	Overview
package.json	Adds the native TypeScript 7 alias and a compiler-version guard while retaining TypeScript 6 for API consumers.
.github/workflows/ci.yml	Runs the new TypeScript version guard before the existing typecheck job.
bun.lock	Locks TypeScript 7.0.2 and its optional platform-specific native compiler packages.
