Fix remaining worker startups for gt seance metadata

- startCrewMember: now uses BuildCrewStartupCommand (was GetRuntimeCommand)
- refinery/manager.go: now uses BuildAgentStartupCommand (was GetRuntimeCommand)

Both now properly inject BD_ACTOR and GT_ROLE so seance can identify
sessions correctly. This completes the seance metadata fix started in
the previous commit.
