v0.14.4 — spinup works on two-tier hosts (protoAgent ≥ 0.78)

Fixed

• portfolio_spinup_team failed with Error binding repo into team config: ENOENT on every current host (#21). protoAgent ≥ 0.78 scaffolds the team workspace config at <ws>/config/langgraph-config.yaml (ADR 0065 two-tier paths); the bind step still read the pre-two-tier root location, the rollback purged the workspace, and the PM retried into a debugging spiral. The config path now resolves per host layout, with the legacy root as fallback. (#22)
