- GitHub Actions: max 4-hour polling with clear timeout error including run URL
- GitLab CI: max 4-hour polling with clear timeout error including pipeline URL
- Remote PowerShell: fix credential split to preserve passwords with colons
(split on first colon only instead of all colons)
- Remote PowerShell: throw clear error when credential format is invalid
- Ansible: validate ansible-playbook binary exists in setupWorkflow
(separate from ansible --version check)
- All timeout errors use core.error() for GitHub Actions annotation visibility

Add four new providers that delegate builds to external CI platforms:
- remote-powershell: Execute on remote machines via WinRM/SSH
- github-actions: Dispatch workflow_dispatch on target repository
- gitlab-ci: Trigger pipeline via GitLab API
- ansible: Run playbooks against managed inventory
Each follows the CI-as-a-provider pattern: trigger remote job,
pass build parameters, stream logs, report status.
