Gsdmvp Phase

Orchestrator role: Parse phase argument, validate phase, gather user story, run SPIDR check, persist mode + story to ROADMAP.md, then route to plan-phase.

TEXT_MODE fallback: Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number.

Flags:

• --force — Allow operating on in_progress / completed phases
• --text — Use plain-text numbered lists instead of TUI menus

• Show MVP-planning status (e.g., ## ✓ Phase N MVP-Planned — vertical slice captured)
• Emit a ## ▶ Next Up heading with /gsd:execute-phase N (TDD execution)
• Use `/clear` then: before the command
• Include a parenthetical: (/clear is safe — /gsd:resume-work restores position from HANDOFF.json if you change your mind)

MVP planning is a deliberate slice-of-the-cake exercise; clearing context before execution keeps TDD focused on the captured story rather than the planning conversation.
