RoleConfig.allowed_scopes was parsed but never enforced. Now an action whose
product is outside the role's allowlist is refused before it reaches the gate,
so an HR-assistant role can't be made to touch code/drive.
- applyRoleConfig fills opts.RoleScopes from the role's allowed_scopes
- the orchestrator gains allowedScopes + scopeAllows(product); empty = allow all
- handleReply refuses an out-of-scope action up front and tells the requester
it is out of the twin's lane (a capability boundary, not an approval, so safe
to surface); nothing reaches the gate or the owner
- launchConnector wires opts.RoleScopes into both orchestrators and logs the
boundary at startup
Tests: out-of-scope refused (not gated), in-scope proceeds, empty = allow all.
