Summary of Changes

Hello @ishaanxgupta, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the AppContainer.tsx component to streamline the invocation of session start and end hooks. By transitioning from direct, conditional calls to a centralized HookSystem wrapper, the change significantly reduces boilerplate code and enhances the clarity and maintainability of the hook management logic within the application's main container.

Highlights

• Hook System Migration: Migrated direct calls to fireSessionStartHook and fireSessionEndHook in AppContainer.tsx to utilize the new HookSystem wrapper methods, centralizing hook management.
• Boilerplate Reduction: Eliminated redundant conditional checks for hooksEnabled and hookMessageBus before invoking session hooks, simplifying the code within AppContainer.tsx.
• Standardized Hook Invocation: Standardized the way session start and end hooks are fired by leveraging config.getHookSystem(), improving consistency and maintainability of the application's core logic.

Code Review

This pull request refactors AppContainer.tsx to use the HookSystem for triggering session lifecycle hooks. The changes successfully replace direct calls to fireSessionStartHook and fireSessionEndHook with the new HookSystem wrapper methods, which simplifies the component's logic and centralizes hook management. The implementation is clean and correct, and I found no issues of high or critical severity. This is a good improvement for code maintainability.
