fix(subsUnion): resolve turf deps by absolute path, not bare specifier

The previous side-effect-import fix didn't work: the app's own npm deps
(installed by `meteor build`) live in programs/server/npm/node_modules,
a SIBLING of programs/server/assets, not an ancestor of it. Node's
require() only walks up parent directories looking for node_modules,
so require('@turf/circle') from the worker asset script could never
find it regardless of what gets imported elsewhere in the app — it
kept failing with "Cannot find module '@turf/circle'" even after that
fix was deployed.

calcUnionAsync.js (Meteor-compiled code, which already knows how to
locate the app's npm deps) now resolves the three turf package paths
itself and hands them to the worker via workerData; the worker
requires them by absolute path instead of bare specifier.

// which plain require('@turf/circle') can never find by walking up parent
