fix: beads task import uses correct bd list arguments (#150)

Apply 3 CodeRabbit review suggestions:
- Rename variables to camelCase (filter_status → filterStatus, bd_args → bdArgs)
- Fix fallback path to respect status filter instead of plain bd list
- Add jq select guard for missing id/title fields with error handling
