We pass the entire "ts" object into plugins. However, we need to make
sure that that object contains the debug compat helpers.
In the old codebase, the deprecated compat code would tack things onto
the actual ts object, after the server code was executed, and later that
same object would be given to plugins.
But in modules, each TS project only sees the view of the "ts" namespace
that their references implied, not the ts object as some sort of
singleton. To ensure that plugins get the debug compat code, we have to
bring that into each project's view of the ts namespace, and not add it
on later in the executable projects.
This adds a "small" d.ts bundler script. This script is very basic,
using Node printing to produce its output. Generally speaking, this is
inadvisable as it completely disregards name shadowing, globals, etc.
However, in our case, we don't care about the globals, and we can opt to
restructure our codebase in order to avoid conflict, which we largely
had to do anyway when we were namespaces and everything was in scope.
This configures the existing build tasks to use esbuild by default. If
using the plain files is desired, passing `--bundle=false` will build
using plain files and still produce a runnable system.
This is only a basic build; a more efficient build is provided later
when gulp is replaced by hereby.
This step converts each file into an exported module by hoisting the namespace bodies into the global scope and transferring internal markers down onto declarations as needed.
The namespaces are reconstructed as "barrel"-style modules, which are identical to the old namespace objects in structure. These reconstructed namespaces are then imported in the newly module-ified files, making existing expressions like "ts." valid.
