Greptile Summary

Added Terminal installation check before launching LSP servers to prevent cryptic errors when Terminal plugin is missing.

Critical Issue:

• Module-level access to strings.terminal_required_message_for_lsp at line 28 of serverLauncher.ts will fail because the global strings object is initialized asynchronously during app startup in main.js, but this constant is evaluated immediately when the module is imported

Translation Issues:

• All 31 non-English language files use English text instead of native translations, which defeats the purpose of i18n for this error message

Confidence Score: 1/5

• This PR will cause a runtime error when serverLauncher.ts is first imported
• The module-level constant TERMINAL_REQUIRED_MESSAGE tries to access strings.terminal_required_message_for_lsp before the global strings object is initialized, which will cause an error or return undefined. This is a critical bug that prevents the feature from working.
• src/cm/lsp/serverLauncher.ts requires immediate fix for the module-level strings access issue
