fix: release 0.4.0 packaging and SRU improvements

- Added IDE/AI folders to .distignore (.gemini, .qoder, .claude, .vscode, .idea, .cursor)
- Added loose zip files and migrations/ folder to exclusions
- Removed AFTER clause from migration for MySQL compatibility
- Normalize whitespace after stripping MARC-8 control characters in SRU titles
