O_NOFOLLOW_ANY probe caches a result on any error

The noFollowAny capability check now always saves a result, counting any error other than EINVAL as working

What

Claude Code tests whether the system supports O_NOFOLLOW_ANY, an option for opening files. It records the answer as noFollowAny. The answer is now always saved:

  • EINVAL error: recorded as "rejected"
  • any other error: recorded as "works"

Before, only EINVAL saved an answer, and any other error left it blank.

Why

The check now always ends with a stored answer, where before it could be left empty after an unexpected error.
