fix: 🛡️ Sentinel: [HIGH] Fix Unsafe Temporary Directory Creation

[Hardonian]

🎯 What: The vulnerability fixed is the unsafe creation of a temporary directory for storing sensitive SSH configurations using os.tmpdir().
⚠️ Risk: The potential impact if left unfixed is that sensitive SSH configs are written to a globally accessible temp directory, exposing it to read and symlink attacks by other users on the host system.
🛡️ Solution: The fix addresses the vulnerability by creating a secure, user-owned base temporary directory under ~/.nemoclaw/tmp with restricted permissions and creating the SSHFS specific temporary directory within it.

WARNING

File	Line	Issue
src/lib/share-command.ts	127	fs.mkdirSync with recursive: true may not apply mode: 0o700 to existing .nemoclaw directory. If intermediate dirs already exist with weak permissions, security guarantee is weakened. Consider checking directory existence separately or using non-recursive mode with explicit permission fixing.

Closing as stale/unsafe to merge. The branch is far behind main, mergeability is dirty, and the only meaningful code delta is a small optional src/lib/share-command.ts hardening hunk that should be carried forward separately if desired.
