Tracking event hardening

[korgon]

• harden tracking events (prevent events from running when responseId not found in controller)
• update beacon.js package version
• update some documentation around beacon in tracker

[Copilot]

Pull request overview

This PR adds defensive guard checks to tracking event methods across all three controller types (Search, Recommendation, Autocomplete) to prevent runtime errors when a responseId is not found in the controller's event tracking state. It also bumps the @athoscommerce/beacon dependency from 1.0.1 to 1.1.0 and updates documentation to point to the correct repository and uncomment previously-TODO sections.

Changes:

• Added !this.events[responseId] guard checks in all tracking event methods (impression, click, clickThrough, addToCart) across SearchController, RecommendationController, and AutocompleteController to prevent events from firing when the responseId is not found.
• Updated @athoscommerce/beacon from 1.0.1 to 1.1.0, which no longer depends on @searchspring/snap-toolbox.
• Updated documentation in README.md and docs/documents.js to reference the correct athoscommerce/beacon.js GitHub repository and uncomment event method documentation.
