Polyfill packages

Drop ancient engines support:
- The baseline is engines about IE11, ES5 with some additions:
  - Basic WeakMap support (no matter bugs, for internal usage only, in polyfills could be fixed)
  - Basic Map and Set support (no matter bugs, for internal usage only, in polyfills could be fixed or completely replaced)
  - Basic %TypedArray%, ArrayBuffer and DataView constructors support (no matter bugs, in polyfills could be fixed)
  - A way of setting a prototype - Object.setPrototypeOf or __proto__
- Examples of supported engines:
  - IE11
  - Chrome 38
  - Safari 7.1
  - FF15
  - Node 0.11
- Examples of no longer supported engines:
  - IE10-
  - Android 4.4.3-
  - PhantomJS (~ IIRC Safari 6.0)
  - Opera Presto (12-)
  - Duktape
- Code changes coming from this:
  - Allow unquoted keyword properties
  - Allow trailing commas in multiline object literals
  - Drop descriptors check
  - Consider strict mode as supported
  - Use native Array.isArray without fallbacks
  - Use native Array.prototype.{ forEach, every, some } without fallbacks
  - Use native Date.now without fallbacks
  - Use native Date.prototype.toISOString without fallbacks
  - Use native Function.prototype.bind without fallbacks
  - Use native Object.create without fallbacks in simple cases
  - Use native Object.getPrototypeOf without fallbacks in simple cases
  - Use native Object.{ defineProperty, defineProperties, getOwnPropertyDescriptor } without fallbacks in simple cases
  - Use native Object.keys without fallbacks in simple cases
  - Use native Object.getOwnPropertyNames without fallbacks in simple cases
  - Use native Object.{ freeze, seal, preventExtensions } without fallbacks in simple cases
  - Use native Object.{ isFrozen, isSealed, isExtensible } without fallbacks in simple cases
  - Consider base JSON methods as existent
  - Drop arguments fallback from Object#toString
  - Drop ES3-related Babel transforms from tests processing
  - Drop workarounds of non-enumerable string chars (IE8-, also affects V8 ~ Node 0.10-)
  - Allow bracket notation on strings instead of .charAt
  - Etc.
  - Consider basic support of WeakMap
  - Consider basic support of Map and Set
  - Consider basic support of ArrayBuffer, DataView and %TypedArray%
  - Consider a way of setting a prototype - Object.setPrototypeOf or __proto__ - as existent
  - Use native Error.prototype.toString without fallbacks (IE8-, V8 ~ Chrome 32-, FF10- bugs)
  - Drop workarounds of V8 ~ Chrome 36- Object.{ defineProperty, defineProperties } bug with prototype
  - Drop workarounds of V8 ~ Chrome 27- non-redefinable__proto__ bug
  - Drop fallbacks to ancient FF iterators (with '@@iterator' string key)
  - Drop a workaround of an IE bug with non-enumerable integer keys on null proto objects
  - Drop a workaround of ancient Nashorn Object.prototype.propertyIsEnumerable bug
  - Drop a workaround for ancient engines whose RegExp.prototype.exec methods don't consistently return undefined for NPCG
  - Drop many and many other fallbacks / workarounds of ancient engines bugs that now make no sense
Remove proposals:
- Withdrawn:
  - Object iteration
  - Getting last item from Array
  - String.prototype.at with code points semantic
  - Math extensions
  - Math.signbit
  - Efficient 64 bit arithmetic
  - URL as a ES proposal, anyway it's left in web standards polyfills
- Dead:
  - New collections methods - without activity from 2018, there are no plans to advance it in its current form, I hope that it will be resurrected soon
  - compositeKey and compositeSymbol - without activity from 2018, anyway the form will be changed, I hope that it will be resurrected soon
  - Number.fromString - without activity from 2018, semantics is not clear
  - String.prototype.codePoints - without activity from 2018
  - Function.{ isCallable, isConstructor } - from 2015 w/o any progress on stage 0, there are no plans to advance it
- Observable (will be replaced with this proposal in the future)
- Seeded pseudo-random numbers because of changing of the API, waiting for the spec text
- Reflect metadata didn't become an official proposal, should be replaced by @@metadata-based logic, see this issue
- If any of those proposals will be resurrected, polyfills can be restored without any problems

Complete refactoring of main library code. The modules that I saw in my nightmares have been completely rewritten.
Reduce minimalistic bundles size
- Optimize export logic
  - Global version
  - Pure version
- Optimize internal dependencies
Move dependencies of many modules to entry points for better optimization by tools like @core-js/builder, babel, swc
Automatically generate core-js entry points, get dependencies from entries definitions and direct declarations from modules - simplification of maintenance, reducing of potential errors and code size
Changes in entry points:
- Make core-js entry an equal of core-js/actual
- Actualize /proposals/ namespace - some proposals were renamed, some entries had some versions
- Drop /features/ namespace in favor of /full/
- Drop /web/ namespace as almost useless in favor of /stable/, /actual/, /full/
- Drop /stage/4, /stage and /proposals entries without specifying a stage / a proposal as almost useless
- Drop */virtual/index.js entries as useless and malicious for exports package.json fields optimization
- Rename the rest /virtual/ entries to /prototype/ for a more telling name
- Drop some other entries that make no practical sense as separate, like /math/to-string-tag
- /proposals/* entries now contain required modules with dependencies
- /stage/* entries now include not only modules from the higher stages than the specified stage but also all stable ES modules
Add exports fields with all entries to package.json
Drop configurable level of aggressiveness from core-js/configurator in favor of future / alternative approaches since the current way is too dangerous, inapplicable in most cases and almost no one uses it

No longer publish on deno.land/x since it's almost dead

Tools:

Move all packages expecting main polyfills packages to scoped packages:
- core-js-compat -> @core-js/compat
- core-js-builder -> @core-js/builder
- core-js-bundle -> @core-js/bundle
- core-js-pure -> @core-js/pure
Move all tools to ESM
Drop Node < 20.19 and 21 support in tools
Add exports fields to package.json of all tools

`@core-js/compat`:

`@core-js/builder`:

Move to rolldown + swc for speedup (~20x)
Add minify option to @core-js/builder, bundles minified by default
Ensure all compatibility with all related updated @core-js/compat options
Make @core-js/builder return an object (for future extensions)

`@core-js/babel-plugin`:

`@core-js/types`:

Prepare the website

That's part of the planned changes, many of the already-done moments are not documented, the rest will be added later.
