sidebar: file tree omits all symlink entries (symlinked directories invisible) #53958

Description

Summary

The review sidebar's file tree omits every symlink entry, so symlinked directories are invisible in the tree even though they exist on disk and in the terminal. The tree is populated from GET /api/fs/list, which returns only real entries: symlinks to directories, symlinks to files, and broken symlinks are all absent.

Environment

• opencode version: 2.0.25
• OS: Linux x86_64
• Terminal: xterm-256color (desktop app connected to a remote server)
• Shell: /bin/bash
• Install/channel: release binary, server started as opencode serve --service
• Active plugins: none

Reproduction

1. Create a scratch directory containing:
   • realdir/ (real directory)
   • realfile.txt (real file)
   • linkdir -> realdir (symlink to directory)
   • linkfile -> realfile.txt (symlink to file)
   • broken -> /nonexistent (broken symlink)
2. Query the listing API for that directory:
   opencode api get '/api/fs/list?path=<scratch-dir>'
3. Inspect the returned data array, or open the sidebar file tree at that directory.

Expected Behavior

Symlink entries should be listed like other entries; at minimum symlinks that resolve to directories should appear as directories and be browsable, matching a normal file explorer. External targets can remain behind the existing permission flow if desired.

Actual Behavior

Only realdir/ and realfile.txt are returned. linkdir, linkfile, and broken are all missing, so no symlink of any kind can appear in the sidebar file tree. Reproduces consistently (100%).

Additional Context

• Same root cause as fix: symlink/junction directories invisible in directory picker and @file #28526 / PR fix(filesystem): resolve symlink/junction targets to directory type in readDirectoryEntries #28532: readDirectoryEntries classifies symlinks, and downstream filters drop non-directory entries. Opening a new issue per the auto-close notice on fix: symlink/junction directories invisible in directory picker and @file #28526.
• The sidebar tree (session review v2, "Filter files") is fed by the file.list client call to /api/fs/list; anything filtered server-side is invisible in the UI.
• All names and paths above are synthetic; no user data included.
