Marshroom start-issue：自动化Git工单处理工具，提升开发效率

筛选购物车条目，其中 repoCloneURL（HTTPS）或 repoSSHURL（SSH）与当前远程仓库匹配。通过从每个条目中提取 owner/repo 进行比较

如果没有匹配的购物车条目，告知用户此仓库没有购物车工单

如果 $ARGUMENTS 包含工单号，则查找该条目；否则，如果有多个匹配项，列出它们并让用户选择一个

运行 git checkout main && git pull origin main 以确保 main 分支是最新的

创建并检出分支：git checkout -b {branchName}。分支名称应为 Feature/#N 或 HotFix/#N。N 是工单号。

更新工单状态（必须）： * 首选尝试：marsh start #{issueNumber} * 如果在 PATH 中找不到 marsh，则回退到直接原子更新：

 STATE_FILE="${MARSHROOM_STATE:-~/.config/marshroom/state.json}"
 TMP="$(mktemp "${STATE_FILE}.XXXXXX")"
 jq --argjson n ISSUE_NUMBER '.cart |= map(if .issueNumber == $n then .status = "running" else . end)' \
   "$STATE_FILE" > "$TMP" && mv -f "$TMP" "$STATE_FILE"

Extract owner/repo from the remote URL (handle both HTTPS and SSH formats)

Filter cart entries where repoCloneURL (HTTPS) or repoSSHURL (SSH) matches the current remote. Compare by extracting owner/repo from each

If no matching cart entries, tell the user this repo has no cart issues

If $ARGUMENTS contains an issue number, find that entry; otherwise if multiple matches, list them and ask the user to pick one

Run git checkout main && git pull origin main to ensure main is up to date

Create and checkout the branch: git checkout -b {branchName} The branch name should be Feature/#N or HotFix/#N. N is issue number.

Update issue status (MANDATORY) : * First try: marsh start #{issueNumber} * If marsh is not found in PATH, fall back to direct atomic update:

 STATE_FILE="${MARSHROOM_STATE:-~/.config/marshroom/state.json}"
 TMP="$(mktemp "${STATE_FILE}.XXXXXX")"
 jq --argjson n ISSUE_NUMBER '.cart |= map(if .issueNumber == $n then .status = "running" else . end)' \
   "$STATE_FILE" > "$TMP" && mv -f "$TMP" "$STATE_FILE"
