Shiny for Python Release Train

Walk through releasing the full py-shiny ecosystem interactively. Each phase requires explicit user confirmation before proceeding to the next.

Interactive Protocol

• Present one phase at a time with its checklist
• After presenting a phase, stop and wait for the user to confirm completion or ask for help
• Use gh CLI for GitHub operations (PRs, releases, tags)
• Track progress with a TodoWrite checklist
• If the user says "skip", mark the phase done and move on
• If a phase fails, help debug before moving on
• Never proceed to the next phase until the current one is resolved or explicitly skipped
• Shut down every long-running process a phase started before marking it complete (see below)

Clean up background processes at the end of each phase
