JSC and QuickJS now implement the V8 Serializer API in order to handle serialization of standard JS types intermingled with Godot variants. On the web things are a bit more complex. We try take advantage of the web's built-in postMessage functionality as much as possible. The browser's postMessage handles structured clone for us i.e. will serialize plain old data, as well as more advanced types like Set, Map etc. However, it can't handle Godot types. So before calling postMessage we descend through the message data structure and replace Godot objects with markers which are delivered via the transfer list (WASM side channel). If a message contains no Godot objects then process is particularly performant because neither the sender or the receiver need to cross the WASM bridge at all when sending/receiving the message. QuickJS-NG has been updated to the latest version. Also, implemented a test matrix for each of our runtimes: - V8 - QuickJS (NG) - JavaScriptCore - Web - QuickJS WASM on Web

Also: - Cleaned up "jsb.editor.codegen" APIs slightly. - Web build fixes. in particular addresses closure compiler (release) web build issues.

QuickJS-NG has been updated to the latest version.
Implemented a test matrix for each of our runtimes:
Godot/GodotJS executable can now be executed with
--headless --editor --generate-typesand it will populatetypings/andgen/directories with engine and project types. Projects may now optionally omit these directories from their Git repos and then perform a bootstrap process:tsc --noCheck) to generate.godotjs/with JavaScript.--headless --editor --generate-typesThe project will these be ready to build as per usual with full type checking. The GodotJS test project now takes this approach during CI as it makes it easier to run the test project against different Godot engine versions (which have different APIs and therefore different types).
