Serialize unit coverage before the combined report.

With make -j, migration/test-unit and migration/report-coverage-all are independent prerequisites of migration/test-coverage-all. No repository Make setting adds ordering between them. The report can check $(UNIT_COVERAGE_PROFILE) before migration/test-unit creates it, so the target can fail. Invoke the report from a recipe after migration/test-unit completes, or add an equivalent ordered dependency.

In `@migration.mk` at line 119, Update the migration/test-coverage-all target so
migration/report-coverage-all cannot run concurrently with migration/test-unit
under make -j; invoke the report from an ordered recipe after
migration/test-unit completes, or add an equivalent dependency using the
existing coverage target symbols.

Coverage is optional because the migration binaries run outside the Go test process. E2E CLI
binaries are always built with `go build -cover`, and the E2E targets collect their coverage
under `artifacts/e2e/coverage`. After both E2E matrices have run, `make migration/test-coverage-all`
merges that CLI data with a fresh unit-test profile and displays the combined result. It fails
if E2E coverage is absent, preventing a misleading unit-only report. Upload the merged profile
under `artifacts/e2e/coverage`. `make migration/test-unit` always writes the unit profile under
`artifacts/coverage`; after both E2E matrices have run, `make migration/report-coverage-all`
merges the existing profiles and displays the combined result. `make migration/test-coverage-all`
reruns the unit suite before displaying that report. The report fails if unit or E2E coverage is
absent, preventing a misleading partial result. Upload the merged profile
and failure artifacts, but do not impose an E2E percentage threshold; the unit suite owns the
≥80% gate. This avoids treating controller waits and external command plumbing as unit
coverage while still showing which migration paths the E2E suite executes.
