fix: cookbook tree runner stdout/stderr separation and bash brace expansion

- Fix bash brace expansion issue with ${2:-{}} defaults causing extra } chars - Redirect step status messages to stderr to prevent JSON output pollution - Redirect wait_pipeline/wait_site/diagnose output to stderr - Add SDLC handler tests for state, features, tasks, artifacts endpoints - Add SDLC classifier tests for phase transitions and blocking - Add SDLC CLI command tests for feature, task, branch, merge operations Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
