chore(memory): improve

[avivkeller]

After this change, during testing, memory didn't exceed ~1.15GB (~630MB without all generation) (before this change, it was 2GB and climbing).

Performs AST -> JS on the jsx-ast worker side, rather than the web main thread, resulting in less information passed between threads.

PR Summary

Medium Risk
Refactors the jsx-ast → web data contract and generation flow; behavior should be equivalent but bundling/SSR paths are touched across the full doc build pipeline.

Overview
Moves JSX AST construction and toJs serialization into jsx-ast workers so the main thread only receives lightweight { data, code } items instead of full ASTs—especially important for the synthetic all page.

Synthetic pages are no longer built eagerly on the main thread (buildSyntheticDescriptors + worker streaming replaces buildSyntheticEntries + a separate yield). The web generator is updated to accept pre-serialized code via createCodeConverter and processBundles (replacing in-process AST conversion in processJSXEntries). Tests mirror worker output with a toCodeItem helper.
