Modernization and error handling

[megastep]

I noticed that this repository hasn't seen any updates in a couple of years, and I ran into issues wit my own projects with regards to error handling that needed to be addressed.

• Upgraded several dependencies (including Jest) and build with Node 22 (20 is deprecated)
• Hardened network error reporting
• Fixed some potential security issues with URL encoding

Pull request overview

This PR modernizes the SDK’s build/test toolchain (Node/Jest/TS), improves resilience of network response parsing and error reporting, and hardens request URL construction by encoding path segments.

Changes:

• Centralized URL construction with per-segment encodeURIComponent to avoid unsafe/unintended path injection.
• Made network response parsing tolerant of empty/non-JSON bodies and added richer JSON-parse error reporting via QonversionError.responseCode.
• Upgraded Node/tooling dependencies and updated CI workflows and unit tests accordingly.

pr-checks.yml sets defaults.run.working-directory: ./sdk, but there is no package.json under ./sdk in this repo. This will fail when the runner uses Yarn classic (v1), which is the default unless you explicitly enable Corepack/pin Yarn. Consider either running Yarn from the repo root (remove the working-directory default), or pinning Yarn via packageManager + corepack enable so Yarn can resolve the project root from subdirectories reliably.

This PR introduces Yarn Berry config (.yarnrc.yml) and updates workflows to rely on Yarn caching, but package.json still doesn’t pin a Yarn version via the packageManager field. That can lead to CI/dev using different Yarn majors (e.g., runner’s Yarn v1 vs local Yarn Berry), producing inconsistent installs. Consider adding packageManager: "yarn@<version>" (and enabling Corepack in CI).
