Resolve merge conflicts: merge gp/add-corpus into gp/rv64im with rv64im taking precedence

[Copilot]

PR#5 (gp/rv64im → gp/add-corpus) was blocked with mergeable_state: dirty because both branches diverged from common ancestor 72f8f61 with incompatible changes to the same files.

Changes

• Merge commit with dual parents: Created a merge commit (cd094f0) with gp/rv64im and gp/add-corpus (b532a93) as parents, making gp/add-corpus an ancestor of gp/rv64im
• Conflict resolution (ours): All four conflicting files resolved in favor of gp/rv64im:
  • Cargo.lock — keeps lock consistent with updated Cargo.toml deps
  • fuzz_tx_consistency.rs — keeps normalize_error wrapping
  • fuzz_tx_consistency_only_valid_data1.rs — keeps normalize_error wrapping
  • src/main.rs — keeps normalize_error wrapping

Once this PR merges into gp/rv64im, PR#5 becomes a clean fast-forward.
