[Code scan] Airflow example contains stale local paths and DAG assumptions #148

Source: Codex global repository scan of deepmodeling/dpti at commit b719828.
Project: DeepModeling Agent Code Scan

Problem
The Airflow example hard-codes a local user path and is not aligned with the README wording. It points to TI_taskflow and a work_base_dir under /home/fengbo/..., so copying it on a clean machine will fail unless the user rewrites private paths and has the matching DAG loaded.

Code references

Reproduction
Try to run examples/airflow.sh in a clean checkout with a normal Airflow setup.

Expected result
Examples should avoid private absolute paths and should name the DAG that the package actually installs or documents for that workflow.
