Pathname recreation silently redirects relative operations from the current directory

[CvvT]

One bug found by Specula:

LiteBox stores CWD as normalized pathname text in Context/ResolvedPath, then cwd_prefix() reserializes that text for later relative operations. If the pathname is removed and recreated, later relative open/openat resolves into the replacement directory instead of preserving the original CWD identity or failing.
