Code Review

This pull request updates QuickJS-NG to version 0.15.1, introducing a version flag (-v/--version) in the CLI, support for dumping nested error causes in the libc error utility, and tests for SharedArrayBuffer growth. It also adds compile definitions for mimalloc and updates the documentation. Feedback on the changes points out a potential issue in the error-dumping logic where an exception returned when retrieving the "cause" property is not handled, which could lead to misleading output.

Important

If JS_GetPropertyStr returns JS_EXCEPTION (for example, if a getter for cause throws an exception or a proxy trap fails), JS_IsUndefined(val) will be false. This causes the loop to print a misleading Caused by: header followed by [exception] in the next iteration. Checking for JS_IsException(val) and breaking early prevents this.

        val = JS_GetPropertyStr(ctx, current, \"cause\");\n        if (JS_IsUndefined(val) || JS_IsException(val)) {\n            JS_FreeValue(ctx, val);\n            break;\n        }
