Update remaining commands to use env-aware role detection (gt-1xsah)

- mail.go: gt mail send --self uses GetRoleWithContext
- molecule_attach.go: detectCurrentAgent uses GetRoleWithContext
- molecule_attach_from_mail.go: uses GetRoleWithContext
- molecule_lifecycle.go: burn/squash use GetRoleWithContext
- rig.go: gt rig reset uses GetRoleWithContext

All role detection now checks GT_ROLE env var first.
