Module codegen needs the same package.json/tsconfig/deno.json writers init
already has — they were the module writers all along, just missing the one
thing codegen adds: the typescript pin.

It is not cosmetic. The runtime mounts its own prebuilt compiler, and skips
dependency installation entirely for an otherwise dependency-free module, only
when the pin matches the engine's default; without it every dagger call pays
for a package-manager install. Deno has no node_modules to fall back on, so it
gets the same pin through its import map.

Both use setIfNotExists, so a module that picked its own version keeps it and
accepts the install rather than being silently retargeted. Existing
expectations updated for the new output, with explicit cases for the
preservation path.

A module's generated package.json and tsconfig.json came out on a single line.
sjson edits in place, which reads as "preserve the user's formatting" but only
holds for the parts it does not touch: keys it adds are appended compactly, and
a file created from scratch — every fresh module — comes out entirely inlined.

Indent everything we write instead, key order preserved. This reformats an
existing file's whitespace, which is a real cost, but these are committed config
files people read and edit; emitting them minified is worse.

Two init assertions had encoded the old output shape ("type":"module" with no
space) and now read the way the file does.
