Create wrapper runCliJson

[mario-campos]

Summary

A few of the CLI commands emit JSON. This PR creates a runCli wrapper function called runCliJson that expects JSON output from the CLI command. This change centralizes and reduces the number of JSON-parsing call sites in codeql.ts, making the code more readable and D.R.Y.er.

Pull request overview

This PR introduces a runCliJson helper in src/codeql.ts to standardize “run CLI command + parse JSON output” behavior, reducing duplicated JSON.parse logic across CodeQL CLI wrapper methods.

Changes:

• Add a generic runCliJson<T> wrapper around runCli that parses JSON output.
• Refactor several CodeQL wrapper methods (e.g., resolve languages, resolve build-environment, resolve queries, resolve database, version) to use runCliJson instead of inlined parsing.
