The getManager() function was returning a literal "<rig>/witness" string
for polecats and refineries instead of substituting the actual rig name.
This caused LIFECYCLE messages to be sent to "@<rig>/witness" instead of
proper addresses like "@gastown/witness".
Fix:
- Add detectRigFromContext() to extract rig from current directory
- Update getManager() to use detected rig name
- Fallback to deacon/ if rig detection fails (safety)
