"""Centralized AstrBot path helpers.

Project path:
- Fixed to the source tree location.

Root path:
- Defaults to the current working directory.
- Can be overridden with the ``ASTRBOT_ROOT`` environment variable.

Data subdirectories:
- Most runtime data lives under ``<root>/data``.
- A few tool-runtime files intentionally live under the system temporary
  directory as ``.astrbot``.
