Fix remaining tempDir references to use runtimeTempDir

TypeScript compilation errors revealed four places that still used tempDir:
- aiService.ts: Early tool creation for sentinel detection
- ipcMain.ts: executeBash IPC handler
- todo.ts: Todo write tool (2 locations)

All now use runtimeTempDir to match the ToolConfiguration interface.
