Prepare repo for GitHub publication

- Add MIT LICENSE file
- Expand .gitignore with standard Rust/Linux entries
- Remove dangling symlinks (breadmancli, breadpadcli) and dev scratchpad (svgs.txt) from git tracking
- Replace unsafe unwrap() calls with expect() in breadman CLI (guarded by prior filter)
