Greptile Summary

This PR is a routine Dependabot bump of TypeScript across the monorepo. packages/cli and packages/core receive a patch update from ^6.0.2 → ^6.0.3, while packages/web receives a larger jump from ^5.8.3 → ^6.0.3 (a full major version upgrade for that package).

Key observations:

• The patch-level bump for cli and core is low-risk and straightforward.
• The packages/web jump from TypeScript 5.x to 6.x is more significant. TypeScript 6.0 introduced breaking behavioral changes (new defaults for module, moduleResolution, esModuleInterop emit, etc.). The web package uses astro/tsconfigs/strict, and Astro 6.x is already a dependency, so compatibility is expected — but the CI astro check and astro build steps should be verified to pass cleanly.
• In package-lock.json, the root node_modules/typescript (5.9.3) is now marked "peer": true. This means a dependency at the root still declares TypeScript 5.x as a peer requirement. Each workspace resolves its own 6.0.3 copy, so no runtime conflict is expected, but it is worth noting that the root-level peer resolution retains the older version.

Confidence Score: 4/5

Safe to merge once CI (especially astro check and astro build for the web package) passes cleanly given the TypeScript 5→6 jump there.

For cli and core this is a trivial patch bump. The only meaningful change is packages/web moving from TypeScript 5.8.x to 6.0.3, which is a major version upgrade and brings potential breaking changes in defaults. However, the project already uses Astro 6.x which targets TS 6 compatibility, and the build/typecheck CI scripts run astro check — if those pass, the risk is minimal.

packages/web/package.json — the TypeScript 5→6 major version upgrade is the most impactful change and should be confirmed by CI.

Important Files Changed

Filename	Overview
packages/web/package.json	TypeScript upgraded from ^5.8.3 to ^6.0.3 — a major version bump for this package, larger than the patch bumps in cli/core. Astro 6.1.6 is already in dependencies, which should support TS 6.x.
packages/cli/package.json	Routine patch bump of TypeScript from ^6.0.2 to ^6.0.3.
packages/core/package.json	Routine patch bump of TypeScript from ^6.0.2 to ^6.0.3.
package-lock.json	Lock file updated: each workspace gets its own 6.0.3 install; root node_modules/typescript (5.9.3) is now marked "peer": true, indicating a peer-dependency resolution at the root level that retains the older version.
