feat(ios): add Swift Package Manager support for Capacitor 6-8

[Geek-Squared]

What's new

This PR adds Swift Package Manager (SPM) support for the iOS plugin, while keeping the existing CocoaPods integration intact.

With CocoaPods entering maintenance mode and its trunk going read-only in December 2026, SPM is becoming the standard for iOS dependency management. Capacitor 8 already defaults to SPM for new iOS projects, so this change ensures freeRASP works seamlessly with modern Capacitor setups.

Changes:

• Added Package.swift with binary target for TalsecRuntime.xcframework and Capacitor/Cordova dependencies (supports Capacitor 6-8)

PR checklist

In-app checks:

• callbacks are received
• dev/prod switch works
• README.md is updated (if applicable)
• example app is working

Pre-release checks:

• CHANGELOG.md is updated
• package.json version is increased
• release label is applied on PR

To be checked by maintainers:

• freeRASP logs are received
• sdkVersion property in logs is correct
• sdkPlatform property in logs is correct

Resolved issues

Adds SPM support in preparation for CocoaPods deprecation (December 2026) and compatibility with Capacitor 8's default package manager.
