angrr now uses TOML configuration, and also adds the ability to define
profile policies.
1. Update the package itself.
2. Update the NixOS module to create, validate, and install config file.
3. Update the NixOS test of angrr to test new functionalities.
1. Starting from v0.1.4, the tool only monitors `result.*` and `.direnv/.*` GC roots.
Modify paths to reflect this change.
2. `test ! -f /path/to/symlink` always succeed because symbol links are not regular file.
Replace all `test ! -f` with `test ! -e`.
