fix: unify PTY process termination handling across platforms

Browse Source 
Refactored the process termination logic in both ClaudeUsageService and TerminalService to use a centralized method for killing PTY processes. This ensures consistent handling of process termination across Windows and Unix-like systems, improving reliability and maintainability of the code.
