Improve Zulip’s Native Integrations and Features around Keyboard and Settings.

For my project with Zulip, I aim to improve its integration ecosystem and core user experience. My project focuses on two primary areas: (1) Secure & Automated Integrations and (2) UX & Accessibility .In alignment with this year’s GSoC focus on security, under integrations, I will strengthen webhook systems by implementing secure payload verification, enabling automated topic resolution for GitHub, improving event handling, and expanding support for external platforms .For UX & accessibility, I will improve keyboard navigation(specifically macOS dropdown support) and refine settings features, including more accurate unread message handling in narrowed views.
