fix(producer): break aws-lambda↔producer build cycle for lambda-local harness

Browse Source 
The aws-lambda publish-readiness changes earlier in this PR moved
aws-lambda's types from `./src/index.ts` → `./dist/index.d.ts`. That
flipped producer's emit pass from "always works" to "needs aws-lambda
built first," because producer's `regression-harness-lambda-local.ts`
imports `@hyperframes/aws-lambda{,/handler}`. aws-lambda's own emit
pass in turn imports `@hyperframes/producer{,/distributed}` → circular
build dependency, so neither side can emit declarations in a single
pass. CI's first run on this PR failed Build, Typecheck, CLI smoke,
windows tests, and every perf job for this reason.

Fix: extract the public surface of `regression-harness-lambda-local.ts`
into a new types-only file that has no aws-lambda imports, point
`regression-harness.ts` at that types file, and exclude
`regression-harness-lambda-local.ts` from producer's tsconfig
`include`. The implementation file is still loaded at runtime via
`tsx` (lambda-local mode runs the harness through tsx, not from
producer's dist/), so the runtime contract is unchanged — producer's
tsc just no longer has to type-check it.

  - `regression-harness-lambda-local-types.ts` (new): exports
    `RunLambdaLocalInput` + `RunLambdaLocalRender` with zero
    aws-lambda imports.
  - `regression-harness-lambda-local.ts`: re-exports
    `RunLambdaLocalInput` from the new types file (so the public
    name stays stable for any future direct imports).
  - `regression-harness.ts`: drops the `typeof import("...")` trick
    and uses the explicit `RunLambdaLocalRender` signature for the
    dynamically-loaded function.
  - `tsconfig.json`: excludes `src/regression-harness-lambda-local.ts`
    so producer's emit pass never resolves `@hyperframes/aws-lambda`.

Verified:

  bun run build                   # full root build green
  bun run verify:packed-manifests # all packages publish-safe
