Replaces CB-592's single hardcoded GITEA_ACCESS_TOKEN shadow in HerdrPeerLauncher with BridgedConfig.MemberCredentials (memberCredentials: policy/allow/known). Every known name not also allowed is overlaid with a sentinel; an unrecognized policy value refuses at load; a credential-shaped host env var on neither list is logged as a gap (name only, never a value). bridged.yaml is gitignored, so the 31 measured names + 4-name allowlist ship as a commented block in bridged.example.yaml for the operator to apply live.
