What is this?
Introduces a filesystem context for Harness and applies it to the GitHub Action so its filesystem-dependent behavior can be tested without host temporary directories.
How does it work?
@react-native-harness/toolsnow provides an AsyncLocalStorage-backed context, a real Node filesystem default, and a memfs-powered testing helper. The GitHub Action establishes that context at its entrypoints, usesgetFs()in migrated code, and keeps runner logic separately callable under an in-memory filesystem.Why is this useful?
Action tests become hermetic and faster to reason about, while the new port creates a consistent path for incrementally migrating the remaining Harness filesystem usage.
Closes #165
