Checkout fails on default Git-for-Windows: tracked paths up to 180 chars overflow MAX_PATH

Describe the bug

git clone of this repo fails at checkout on a default Git-for-Windows install whenever the clone destination is a moderately deep directory. The longest tracked path is 180 characters:

trajectories/demonstrations/replay__marshmallow-code__marshmallow-1867__default_sys-env_cursors_window100__t-0.20__p-0.95__c-2.00__install-1/marshmallow-code__marshmallow-1867.traj

so with Windows' 260-character MAX_PATH there are fewer than 80 characters left for the clone root. A clone under e.g. a OneDrive-redirected profile, an org folder tree, or any CI/tool workdir deeper than that gets a repo whose working tree is silently incomplete (clone "succeeds", checkout fails). Enabling LongPathsEnabled=1 in the OS does not help — Git-for-Windows has its own core.longpaths setting, which defaults to false.

Steps/commands/code to Reproduce

git clone https://github.com/SWE-agent/SWE-agent.git

from any directory whose absolute path is ≳80 characters (mine was 115).

Error message/results

warning: Clone succeeded, but checkout failed.

Workaround that recovers it:

git clone -c core.longpaths=true https://github.com/SWE-agent/SWE-agent.git

Possible fixes, smallest first: mention the flag in the install/development docs; or shorten the trajectories/demonstrations directory names, which contribute the worst offenders (180, 176, 176, 172, 168 characters).

Happy to PR either.
