Context

cli/python/base_release/engine.py combines release argument parsing, context construction, check/plan/notes/publish command handling, and Homebrew handoff rendering. The publish path is important enough to isolate parser and orchestration responsibilities.

Scope

• Extract release argument parsing or command rendering/publish orchestration into focused modules.
• Keep release command behavior stable.
• Preserve existing recovery guidance and Homebrew handoff text.

Validation

• Focused release parser/publish tests.
• Existing release tests.
• git diff --check.
