Creates the new src/lib/rollups/ aggregator directory and relocates
the main measurement rollup module:
- src/lib/measurements/rollups.ts → src/lib/rollups/measurement-rollups.ts
- src/lib/measurements/__tests__/rollups.test.ts →
src/lib/rollups/__tests__/measurement-rollups.test.ts
Every importer of @/lib/measurements/rollups is rewritten to
@/lib/rollups/measurement-rollups. The orphan sibling reference inside
src/lib/measurements/rollup-read.ts (still in its old home until the
next batch) is promoted to the @/lib alias so the chain keeps
typechecking through the in-flight move.
Pure relocation — no behaviour change, no exported-surface change. The
umbrella exists so the rollup contract is discoverable from a single
directory before the iOS sprint locks the boundary.
