Greptile Summary

This PR bumps typescript from 5.9.3 to 6.0.2 (a major version jump), but does not include the required tsconfig.json changes needed for TypeScript 6.0 compatibility, which will break the build.

Key concerns:

• Build-breaking: missing \"types\": [\"node\"] in tsconfig.json — TypeScript 6.0 changes the default value of the types option from auto-discovering all @types/* packages to an empty array ([]). The project relies heavily on Node.js globals (process.env, process.exit, process.stdin, process.argv, process.platform, process.cwd()) that come from @types/node ambient types. Without explicitly setting \"types\": [\"node\"] in tsconfig.json, the build (tsc) will fail with Cannot find name 'process' across many source files.

• Other TypeScript 6.0 defaults are already compatible — The tsconfig.json already explicitly sets strict: true, target: \"ES2020\", module: \"NodeNext\", moduleResolution: \"NodeNext\", rootDir: \"src\", and esModuleInterop: true, so those new TypeScript 6.0 defaults do not cause additional issues for this project.

• Recommendation — Add a \"types\": [\"node\"] entry to compilerOptions in tsconfig.json before or alongside this merge.

Confidence Score: 4/5

Not safe to merge without a companion tsconfig.json fix — the TypeScript 6.0 types: [] default will break the build

The dependency bump triggers a real breaking change (TypeScript 6.0 types defaulting to []) that will cause tsc to fail on every process.* usage in the codebase. This is a concrete, reproducible build failure, not a speculative concern. All other TS 6.0 breaking defaults are already mitigated by the existing tsconfig.json explicit settings.

tsconfig.json needs "types": ["node"] added to compilerOptions to restore Node.js ambient type availability under TypeScript 6.0

Important Files Changed

Filename	Overview
package.json	Bumps the typescript devDependency version constraint from ^5.5.0 to ^6.0.2; triggers a major-version upgrade with multiple breaking default changes (most critically types: []) that will break the current tsconfig.json
package-lock.json	Lock file updated to resolve typescript from 5.9.3 to 6.0.2; no issues in the lockfile itself

   TypeScript 6.0 breaks build: types now defaults to []

   TypeScript 6.0 changes the default value of the types compiler option from auto-discovering all @types/* packages to an empty array ([]). This means @types/node — listed in devDependencies — will no longer be automatically included, causing type errors across the entire codebase.

   The source files use process as a global in at least 15+ locations (e.g., process.env, process.exit, process.stdin, process.argv, process.platform, process.cwd()), all of which are provided by @types/node ambient declarations. Without "types": ["node"] in tsconfig.json, the TypeScript compiler will emit errors like Cannot find name 'process', breaking the npm run build step entirely.

   The Microsoft TypeScript 6.0 announcement explicitly states: "This will affect many projects. You will likely need to add \"types\": [\"node\"]"

   The fix needs to be applied to tsconfig.json (which this PR does not modify):

   {
     "compilerOptions": {
       "target": "ES2020",
       "module": "NodeNext",
       "moduleResolution": "NodeNext",
       "outDir": "dist",
       "rootDir": "src",
       "strict": true,
       "esModuleInterop": true,
       "declaration": true,
       "skipLibCheck": true,
       "types": ["node"]
     },
     "include": ["src"]
   }

   This PR should be held until a companion tsconfig.json change is included (or merged separately first).
