Fix formatting in task-planner.agent.md

[hunterhogan]

Without the space before the comma, VS Code interpreted the comma as part of the file name, which caused the following error even though the target file was in the target location:

File './task-researcher.agent.md,' not found at 'C:\Users\hunte\AppData\Roaming\Code - Insiders\User\prompts\task-researcher.agent.md,'.

After adding the space, the yellow squiggles and error went away.
