Fix Nx build output paths

[isaacroldan]

Summary

• Point Nx build outputs at each package-local dist directory
• Leave generated/docs output declarations unchanged

Validation

• JSON parsed changed project.json files
• git diff --check
• prettier --check changed project.json files

Notes

• nx show project could not run from this dependency-less worktree using another checkout's Nx because module resolution follows this worktree and node_modules is absent.
