Subject: [PATCH] fix: replace + with - in bundle identifier for UTI
 compatibility (issue #87)

- Rename package from UITextView+Placeholder to UITextView-Placeholder
- Add Tuist+SPM integration test to CI workflow
- Update SPM integration test script with correct product name
- Add new test script to reproduce and validate the fix
- Bundle identifiers must use alphanumeric, hyphen, and period chars only
- SPM converts hyphens to underscores for module names (non-breaking)
