fix(terminal): check file timestamps on terminal-job exit #41814

Problem:
When a `:!` command runs, file timestamps are checked and W12 or
`FileChangedShell` is triggered. But not when a `:terminal` job exits.

Only `enter_buffer()` checks, so whether you get the W12 warning depends
on how you happen to return to the file: `:term` works, `:tabnew | term`
does not.

    echo foo > testfile
    nvim --clean testfile
    " Edit the buffer, don't save it.
    :!mv testfile testfile2
    :tabnew | term sh
    touch testfile2 && mv testfile2 testfile
    exit

'autoread' is defeated because `:!mv` deletes the file, so
`should_watch()` fails and the watcher stops. `ensure_watcher()` only
re-runs on `BufReadPost`/`BufWritePost`/`OptionSet`, so nothing watches
the file when the terminal moves it back.

Solution:
Set `need_check_timestamps` on terminal-job exit, same as `:!cmd`
(`os_shell`).
