If file was a symlink whose target moved to a different VC tree (shared drives, CI workspaces), the key was unchanged and the cache kept serving the old branch/state. Added the resolved file-truename to the key, so a symlink re-pointed at a new target produces a different key and the cache refreshes. The extra file-truename is one stat per modeline refresh, cheap next to the VC calls the cache exists to avoid. Tests cover truename inclusion, key stability for an unchanged file, and a symlink whose target moves.
