Clearer error when a working directory path is invalid

You'll notice
Useful2 Signal1
Permissions

Adding a working directory now says whether the path is unresolvable, missing or malformed.

What

Adding a working directory now separates a path that cannot be resolved at all from one that simply does not exist, and calls out paths containing a null character with their own message.

Details
  • New invalid-path outcome alongside the existing not-found outcome.
  • Null-byte paths are reported as unusable as a working directory rather than as missing.
Evidence

contains a null character, so it can't be used as a working directory

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
