resolveUnderRoot already blocked path-layer traversal but explicitly
did NOT follow symlinks — a repo symlink config -> /etc/shadow
passed the containment check because the link path was under root.
clide would then read the target.
Add resolveUnderRootFollowingSymlinks: resolves any symlinks at the
target and re-verifies containment against the resolved real root.
The split keeps pure path math testable without filesystem access.
files.read and files.ls now route through it.
Tests cover: plain non-symlink passthrough, non-existent target
(returns path-layer result so caller surfaces not-found cleanly),
single-hop and chained symlinks whose targets escape the workspace,
and tolerance of symlinks in the root path itself (macOS /tmp).
Also adds the T-101 CHANGELOG entry that the docs commit missed.
