libpanto API fixes

- FSJSONLStore: don't require `cwd`, instead panto CLI provides it in
  the session metadata
- Lua: expose the `SessionStore` interface and the `FSJSONLStore` and
  `NullStore` implementations
- C: use idiomatic `const char *` for incoming strings
- C: expose the `FSJSONLStore` and `NullStore` implementations
