Add checkpoint-based FpgaDiff rebuild flows to reduce iteration time for DiffTest-only changes.

  • add whole-project incremental synthesis and implementation with reusable synth/routed DCPs
  • add CPU-DCP and subpartition reuse flows with RTL/interface compatibility checks
  • keep manifests, reuse reports, and dry-run support with the incremental outputs

CPU-DCP reuse requires a compatible CPU and partition interface; the whole-project flow remains the fallback.
