classifyDotGit() checked with lstat and then opened by name, so a FIFO
swapped in between the two blocked a threadpool worker. The open itself
now refuses both, and the handle is judged.
Reported on #772.

The lookup judges liveWorktree.path lexically and only when the pane moves,
while the route's probe and readdir both follow symlinks. A symlink put at
that path, or at a parent of it, without moving the pane re-rooted the listing
outside workingDir. Names and sizes leaked, while file-content and file-raw
still refused the paths.
The route now resolves both folders on every request and walks the worktree
only when it lies strictly inside the resolved workingDir, otherwise it walks
workingDir. Only the check uses the resolved paths: the walk keeps the session's
spelling, so a workspace reached through a symlink still gets paths relative
to workingDir.

Claude Code's EnterWorktree moves the running process into
<repo>/.claude/worktrees/<name>, while Session.workingDir stays on the main
checkout. The Files panel kept walking workingDir, so it listed a tree the
agent had left.
paneCwd already follows the move, measured on Claude Code 2.1.318 in both
directions, so nothing new has to track the agent. It also follows every cd
in a shell, so a new SessionState.liveWorktree narrows it to a linked
worktree, read from the .git file without starting git.
Only a folder strictly below workingDir is ever an answer, and the listing
only starts there: returned paths stay relative to workingDir, so the
preview, raw and edit routes are unchanged and confinement does not widen.
A worktree outside the session folder stays unfollowed.
The panel asks with root=live, shows a strip naming the worktree with a
switch to the session folder, and follows the agent in and out while open.
