[BUG] Plan mode cannot read files from SSHFS/FUSE mounts (regression)

What's Wrong?

Description:

• Normal mode reads SSHFS-mounted directories fine
• Plan mode sees only empty directory stubs
• Read tool returns "file does not exist"
• Glob returns no results
• ls via Bash shows directory structure but no files
• Started this week

What Should Happen?

In non-plan mode it accesses SSHFS-mounted directories fine. Plan mode now cannot find them.

Error Messages/Logs

Steps to Reproduce

1. Have an SSHFS mount at /home/user/cloudbox_moveblock pointing to remote moveblock@cloudbox:~/moveblock
2. In normal Claude Code mode, verify files are readable:

# Works fine - returns file content
Read /home/user/cloudbox_moveblock/_visibility/runtime/plans/ACTIVE/EXTRACTION_PROCESS_V2/extraction_bible.yaml

1. Enter plan mode (/plan or however triggered)
2. Attempt same read:

Read /home/user/cloudbox_moveblock/_visibility/runtime/plans/ACTIVE/EXTRACTION_PROCESS_V2/extraction_bible.yaml
# Returns: "File does not exist"

1. Bash ls shows empty stubs:

ls -la /home/user/cloudbox_moveblock/
# Shows only: _visibility (empty directory structure, no actual files)

1. Glob returns nothing:

Glob **/*.yaml in /home/user/cloudbox_moveblock/
# Returns: "No files found"

Expected: Plan mode should have same filesystem access as normal mode.

Actual: SSHFS mounts appear as empty directory trees in plan mode.

Environment:

• Linux 6.6.87.2-microsoft-standard-WSL2
• Claude Code (current version as of 2025-11-28)

Workaround: Use ssh cloudbox "cat <path>" via Bash tool to access files.
