Tyler Slaton 7673b8dfb8 fix(build): load tsdown exports helper as .mjs under native config loader
CI build runners use a Node with native TypeScript stripping enabled
(process.features.typescript), so tsdown selects its native ESM config
loader. That loader cannot resolve the extensionless relative import
"../../scripts/tsdown-exports" in each tsdown.config.ts, so every package
build failed with "Cannot find module" — cascading into the unit, runtime,
and all integration jobs (which run the build first). Local builds used
tsdown's bundler loader instead, which is why this passed pre-push.

Ship the shared helper as scripts/tsdown-exports.mjs (real ESM) plus a
hand-written tsdown-exports.d.mts, imported with the explicit .mjs
extension. This resolves under the native loader, tsdown's bundler loader,
and tsc alike. The generated exports are unchanged — package.json maps stay
identical.
