feat(wfassoc): enhance CLSID handling and parsing

- Add `getrandom` dependency for UUID v4 feature
- Enable UUID v4 feature in `Cargo.toml`
- Implement `Clsid::with_random()` for generating random CLSIDs
- Improve `Clsid::new()` to accept `&Uuid` directly
- Update `Clsid::from_str()` to use `uuid::fmt::Braced` for stricter parsing
- Add comprehensive tests for valid and invalid CLSID strings
- Fix minor typo in test assertion code
- Enhance documentation comments for CLSID struct and error type
