Fix real codegen bugs: unused proto import, missing runtime deps, no barrel index

protoc warned that print_job.proto imported template.proto without using it
- removed. ts-types/package.json was missing protobufjs and long, which the
ts-proto-generated code imports at runtime - tsc failed with 'cannot find
module'. src/index.ts also re-exports './generated' as a namespace, but
ts-proto wasn't configured to emit an index barrel file for it - added
outputIndex=true to the protoc invocation.

Verified with a clean 'bun run build' (both TS and Rust codegen) and
'tsc -b'.
