Migration Ledger: Detailed Execution & Validation Tracking

This ledger strictly enforces that all tests are explicitly run and validated throughout the atomic migration steps. A phase cannot be marked complete until both the implementation PR has merged and the corresponding test matrix validations are explicitly verified as passing locally and in CI (including multi-platform gn check across Fuchsia, Android, and host toolchains).
