commit 5fbd71374af6fcbdf415765ab7001f4a7a6d7322

Resolver GOT_AUTHOR automáticamente desde git config si el repo no lo define

got.conf de un repo recién clonado solo trae el remote, no un author, así
que got commit fallaba con "GOT_AUTHOR environment variable is not set"
en cualquier repo clonado sin configuración manual previa. Ahora se
resuelve user.name/user.email vía git config como fallback -- got.conf y
la config local del repo siguen ganando por precedencia, así que esto
nunca pisa un author explícito. Confirmado en vivo contra un repo real.
