chore(deps): Pin and update development dependencies

[askpt]

Pin versions of several development dependencies in package.json and update others to their latest versions to ensure compatibility and stability. This includes updates to ajv, brace-expansion, @types/node, and typescript.

Pull request overview

This PR updates the extension’s npm dependency versions to be fully pinned (no caret ranges) and refreshes several dev/transitive packages for more deterministic installs.

Changes:

• Pin all devDependencies and dependencies to exact versions in package.json (including a TypeScript major bump).
• Align package-lock.json with the pinned ranges and refresh transitive packages (e.g., ajv, brace-expansion).
