TS: Array setters/getters for unbounded (max: *) slices

[ryukzak]

Summary

• For slices with max: * (unbounded), setter accepts an array and getter returns an array
• For max: 1 slices, keep existing single-element API unchanged
• Added getArraySliceAll / setArraySliceAll runtime helpers to profile-helpers.ts

Before (unbounded slice like OrganizationEntry):

bundle.setOrganizationEntry({ resource: org1 });
bundle.setOrganizationEntry({ resource: org2 }); // replaces org1!
const entry = bundle.getOrganizationEntry(); // single item

After:

bundle.setOrganizationEntry([{ resource: org1 }, { resource: org2 }]);
const entries = bundle.getOrganizationEntry(); // array of items

Closes #125
