🛡️ Sentinel: [HIGH] Enforce secure file and directory permissions#1
Conversation
Severity: HIGH Vulnerability: The application creates sensitive files (wallets, snapshots) using `fs::create_dir_all` and `fs::write` which default to the system's `umask`, potentially exposing them to other local users. Impact: Local privilege escalation or exposure of wallet secrets on shared Unix-like systems. Fix: Created secure wrappers using `DirBuilderExt` and `OpenOptionsExt` to enforce `0o700` and `0o600` permissions respectively. Updated usages in `src/paths.rs`. Documented the learning in `.jules/sentinel.md`. Verification: Compile and verify permissions on Unix systems. Co-authored-by: bitcoiner-dev <75873427+bitcoiner-dev@users.noreply.github.com>

This PR introduces secure file permission enforcements when creating the CLI's configuration directories and saving sensitive files (like wallet profiles and snapshots). By utilizing Unix-specific
DirBuilderExtandOpenOptionsExt, the application explicitly requests0o700(for directories) and0o600(for files) permissions, preventing local users from reading or tampering with these files on shared machines.This change documents the security pattern within
