refactor(config): use safeMkdirSync for directory creation

Replace manual EEXIST error handling with safeMkdirSync from
@socketsecurity/lib/fs. This simplifies the code and ensures
consistent error handling for directory creation.

Changes:
- Import safeMkdirSync from @socketsecurity/lib/fs
- Replace try-catch blocks around mkdirSync with safeMkdirSync calls
- Remove duplicate EEXIST error handling code

Benefits:
- Cleaner, more maintainable code
- Consistent error handling across the codebase
- Automatic handling of race conditions in concurrent scenarios

Dependencies:
- Requires @socketsecurity/lib with safeMkdirSync support
  (committed in socket-lib: feat(fs): add safeMkdir and safeMkdirSync)
