Bumps core-js from 3.49.0 to 3.50.0.

Release notes

Sourced from core-js's releases.

3.50.0 - 2026.08.05

• Changes v3.49.0...v3.50.0 (138 commits)
• Joint iteration proposal:
  • Built-ins:
    • Iterator.zip
    • Iterator.zipKeyed
  • Moved to stable ES, May 2026 TC39 meeting
  • Added es. namespace modules, /es/ and /stable/ namespace entries
• Iterator chunking proposal:
  • Built-ins:
    • Iterator.prototype.chunks
    • Iterator.prototype.windows
  • Throw a TypeError instead of RangeError on non-integer number chunkSize / windowSize, following [tc39/proposal-iterator-chunking/#30](tc39/proposal-iterator-chunking#30)
  • Moved to stage 3, May 2026 TC39 meeting
  • Added /actual/ namespace entries, unconditional forced replacement changed to feature detection
• Added Iterator includes stage 3 proposal:
  • Added built-in:
    • Iterator.prototype.includes
• Added Iterator join stage 3 proposal:
  • Added built-in:
    • Iterator.prototype.join
• Added Await dictionary of Promises stage 3 proposal:
  • Added built-ins:
    • Promise.allKeyed
    • Promise.allSettledKeyed
• Throw a RangeError on finite unsafe integer limit in Iterator.prototype.{ drop, take }, following [tc39/ecma262/#3776](tc39/ecma262#3776)
• Use PromiseResolve semantics in Promise.try, following [tc39/ecma262/#3883](tc39/ecma262#3883)
• Added detection of missed Webkit ~ Safari < 26.2 Iterator.prototype.flatMap bug case, #1538
• Deno 2.9+ replaces Object.prototype.__proto__ instead of removing it, so the feature detection updated
• Fixed JSON.stringify polyfill with an array replacer - keys order now follows the replacer, inherited and non-enumerable properties are no longer ignored, #1539
• Make URL / URLSearchParams parsing a little more correct (char sets, percent coding, etc)
• Ensure opaque paths always roundtrip in URL polyfill (still without adding to feature detection), whatwg/url#844
• Fix URL#toJSON when URL#toString is reassigned after core-js is imported
• Fixed possible crash on some keys in Symbol.for
• Some get-iterator / get-iterator-method fixes
• Fixed String.prototype.{ match, search } polyfills conversion order
• Added missed MAX_SAFE_INTEGER excess check in Array.from and { Map, Object }.groupBy polyfills
• Improved the way of inner iterators cleaning in iterator helpers
• Improved accuracy of Math.{ asinh, cbrt, log1p } polyfills with big and small values
• Improved performance of Uint8Array base64 methods
• Improved performance of escape
• Slight performance improvement for engines with native Array.prototype.fill on ArrayBuffer constructor and %TypedArray%.prototype.fill
• Clarify supported Node versions in package.json of some missed packages (just to satisfy publint)
• Compat data improvements:
  • Following [tc39/ecma262/#3776](tc39/ecma262#3776), Iterator.prototype.{ drop, take } properly supported from:
    • V8 ~ Chrome 150
    • Safari 27.0
    • Bun 1.4.0
  • Following [tc39/ecma262/#3883](tc39/ecma262#3883), Promise.try marked as not properly supported in all engines
  • Iterator.prototype.{ chunks, windows } marked as shipped in FF154

... (truncated)
