Subject: [PATCH] store dev PDS data outside /tmp

macOS periodically deletes files from /tmp that haven't been
accessed in ~3 days. The @atproto/dev-env PDS stores actor signing
keys as plain files, so after a few days without writes the key
disappears and every putRecord fails with InternalServerError.

Setting TMPDIR to ~/.local/share/starhaven-dev-pds before starting
the PDS process causes os.tmpdir() to resolve there, putting all
PDS data in a location macOS will not clean up.
