chore: remove stale Carthage and semantic-release artifacts

Carthage is no longer a supported distribution method and semantic-release
is no longer used. Remove the Carthage binary manifest, build scripts,
semantic-release config, and all documentation references.

- Delete Scripts/carthage.sh, Scripts/release.sh, release.config.js,
  mParticle_Apple_SDK.json
- Remove Carthage installation section and kits table column from README.md
- Update AGENTS.md to reflect SPM + CocoaPods only distribution
- Remove carthage.sh chmod from SwiftExample/README.md
- Remove Carthage JSON manifest step from sdk-release-maintenance-branch.yml
