improvement: change default agent hook installation top stop hooks

[gabimoncha]

i've been a react-doctor user since it's launch

i've noticed that on some longer sessions and a lot of uncommitted files, react-doctor took around 4s to finish

the reason is that the default installation is PostToolBatch for Claude and PostToolUse for the rest of the harnesses

it would be more token efficient and faster, if the hook runs after the agent stops if the call would be inside a Stop hook

also in my case particular case running the cli with --scope changed --include-untracked would include all the files of the run
