Add milestone assignment step to the PR workflow for major specification changes.
The architecture-pool-supervisor agent now assigns created PRs to the current active
milestone using forgejo_update_pull_request, improving traceability and ensuring
spec PRs are properly tracked within project milestone planning.
Changes:
- Add 'PR Workflow for Major Changes' section to architecture-pool-supervisor.md
- Document milestone assignment using forgejo_update_pull_request
- Document milestone querying using forgejo_list_repo_milestones
- Add graceful error handling for missing active milestones
- Add support for multi-milestone spec PRs (use earliest milestone)
- Allow forgejo_update_pull_request in agent permissions
- Add comprehensive BDD tests for milestone assignment feature
