fix: strip quotes when splitting ckb-debugger argv (fixes #494)

[humble-little-bear]

Fixes #494

Problem

offckb debug fails with ENOENT on the tx-file path after the native ckb-debugger switch (PR #491):

Error: Os { code: 2, kind: NotFound, message: "No such file or directory" }
Command failed: ckb-debugger --tx-file "/path/to/full-transactions/0x....json" --cell-index 0 ...

Root cause: CKBDebugger.runRaw() split the command-line string on spaces and passed the tokens as array argv to execFileSync. Array argv does not run through a shell, so the literal quotes that encodeBinPathForTerminal() wraps around space-containing paths are not stripped — ckb-debugger receives a file name that literally contains " characters, hence ENOENT. The pre-#491 code went through execSync("ckb-debugger " + args.join(' ')), where the shell stripped the quotes, so this never surfaced before.

Fix

runRaw() now splits quote-aware: a quoted segment stays one argv element and the surrounding quotes are stripped. This fixes the ENOENT while preserving the original purpose of the quotes — keeping space-containing paths (e.g. --tx-file "/path/with space/tx.json") intact through the string interface.

Verified with the reproduction from the issue report: --tx-file "/path.json" now reaches execFileSync as ['--tx-file', '/path.json'].

Tests

• 3 new unit tests in tests/ckb-debugger.test.ts covering: quoted path (the regression), quoted path containing spaces, and unquoted args pass-through.
• Full suite: 38 suites / 341 passed, ESLint and tsc --noEmit clean.
• Changeset added (patch).

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Fixed offckb debug failing when transaction-file paths contain spaces.
  • Improved command-line handling so quoted paths are correctly treated as single arguments.
  • Preserved existing behavior for unquoted arguments.

Walkthrough

CKBDebugger.runRaw now parses quoted command-line arguments before passing them to execFileSync. Tests cover paths with spaces, quote removal, and unchanged unquoted arguments. A patch changeset documents the transaction-file path fix.

Changes

Debugger argument parsing

Layer / File(s)	Summary
Quote-aware runRaw execution src/tools/ckb-debugger.ts, tests/ckb-debugger.test.ts, .changeset/debug-tx-file-quotes.md	runRaw keeps quoted paths with spaces as single arguments and removes surrounding quotes. Tests verify quoted and unquoted argument handling. The changeset documents the patch release.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🔵 Low · up to 14f49

The change fixes quoted transaction-file paths, but paths containing embedded double quotes may still be passed incorrectly and cause debugger failures. This is a bounded edge case suitable for explicit owner follow-up.

encodeBinPathForTerminal and runRaw so paths containing embedded double quotes
are handled safely as a single argv element, either by escaping and correctly
unescaping those quotes or by rejecting such paths before execution. Add
regression coverage for an embedded-quote path.
