Pull request overview

This PR replaces the previous ckb-transaction-dumper binary dependency with an in-repo implementation based on @ckb-ccc/core, intended to produce the same mock-tx JSON output for downstream debugging tooling.

Changes:

• Rewrote src/tools/ckb-tx-dumper.ts to resolve inputs/cell-deps via a ccc RPC client and decode dep_group via molecule codecs.
• Removed ckb-transaction-dumper from dependencies and updated the lockfile accordingly.
• Added a changeset and added .sisyphus/* plan/session artifacts.

src/cmd/debug.ts:17

• debugTransaction is now async, but the debugRaw(...) calls inside the loop are not awaited. This causes the function to resolve before the debugger runs/finishes, which can lead to the CLI exiting early and/or unhandled promise rejections. Await each debugRaw call (or collect and await Promise.all(...) if parallel execution is intended).

  for (const opt of opts) {
    logger.section(opt.name, [], 'info');
    debugRaw(`${txFile} ${opt.cmdOption}`);
  }

src/cmd/debug.ts:65

• debugSingleScript is now async, but the debugRaw(...) call isn't awaited. This makes the command return before the debugger completes and can cause the process to exit early. Await the debugRaw promise here.

  const txFile = await buildTxFileOptionBy(txHash, network);
  let opt = `--cell-index ${cellIndex} --cell-type ${cellType} --script-group-type ${scriptType}`;
  if (bin) {
    opt = opt + ` --bin ${bin}`;
  }
  debugRaw(`${txFile} ${opt}`);
}
