Worked on the eclipsesource/theia repository to improve the stability and memory management of the Status Bar Message Registry. Addressed a memory leak by refining how disposables are managed, ensuring that resources are only allocated for genuinely new entries and preventing redundant disposals that previously led to leaks. Enhanced the logic for detecting new entries by checking for missing IDs in the entries map, which resolved a bug introduced in an earlier pull request. These changes, implemented in TypeScript with a focus on debugging and memory management, reduced runtime memory growth and improved the reliability of the user interface during extended sessions.
