v6.3.0

Security Fixes

• Upgraded dev-dependency np package version to 11.1.0
• Upgraded dev-dependency jest package version to 30.3.0

Bug Fixes

• Narrowed browser-like output handling to ignore fake process.stdout.write(...) shims in hosts like code.esm.sh, preventing recursive console.log(...) loops and Maximum call stack size exceeded while preserving direct stdout writes in real Node.js. See details in docs/code-esm-sh-stdout-recursion.md

Improvements

• Made the Jest contributor/test stack ESM-aware without changing library runtime behavior. Jest now transpiles the ESM-only chai package via ts-jest, uses a dedicated tsconfig.jest.json, and keeps the test environment on the existing CommonJS semantics so logger startup behavior stays stable under test.
• Refreshed the contributor toolchain around the Jest migration by upgrading ts-jest, chai, @types/jest, @types/chai, sinon, @types/sinon, @types/node, prettier, and typescript, while pruning stale unused test/dev dependencies from package.json.
• Added TypeScript 6 build compatibility by setting ignoreDeprecations: "6.0" in tsconfig.json, keeping the existing emit target and broader library compatibility intact.

Tests

• Added regression coverage for the browser-like fake-stdout recursion case in both the Node-simulated compatibility tests and the real browser bundle tests.
• Updated the Jest test suite to use ESM-safe imports where needed so the upgraded Jest/Chai toolchain runs cleanly end to end.
