Subject: [PATCH] shelley: fix git repo detection using wrong directory

Prompt: evaluate and fix https://github.com/boldsoftware/shelley/issues/71 . The agent has been given a working directory; maybe we're checking the wrong directory to see if it's a git repo?

collectGitInfo() was running `git rev-parse --show-toplevel` without
setting cmd.Dir, so it checked the server process's cwd instead of the
user's working directory. This caused the system prompt to incorrectly
say "Not in a git repository" for VMs where the user's project was in
a git repo but the server process ran from a different directory.

Fixes https://github.com/boldsoftware/shelley/issues/71
