fix(controller): clarify leaderWorkerSpec runtime hardcode (#761)

[nillikechatchat]

Summary

This PR adds a clarifying comment to leaderWorkerSpec() in the team controller, explaining why the Runtime is hardcoded to "copaw":

1. LeaderSpec has no runtime field defined in the API types
2. The team-leader-agent/ template only ships a CoPaw build

Background

Issue #761 reported that Team member Workers were ignoring the runtime field and always using "copaw". The main fix for this issue (changing teamWorkerSpecToWorkerSpec() to pass through w.Runtime) was already applied in the upstream repository.

This PR addresses the secondary request in the issue comments to add a comment explaining the intentional hardcode in leaderWorkerSpec().

Changes

• hiclaw-controller/internal/controller/team_controller.go: Added explanatory comment above leaderWorkerSpec() function

Related Issues

• Team member Worker runtime is hardcoded to "copaw", ignoring TeamWorkerSpec.Runtime and HICLAW_DEFAULT_WORKER_RUNTIME #761 (Team member Worker runtime is hardcoded to "copaw")
• feat(hiclaw-controller): honor spec.env on Worker/Manager/Team CRs #690 (same pattern of Team CR field dropping for spec.env)
