refactor: merge Proposal 4 into Proposal 3 in presentation commands cleanup plan

- Merged 'Extract User Output Helper' into 'Extract Shared Command Dependencies'
- Added UserOutput to CommandContext alongside repository and clock
- Kept report_error() utility function for consistent error formatting
- Reduced total proposals from 12 to 11
- Renumbered all subsequent proposals (5→4, 6→5, etc.)
- Updated all cross-references and dependencies
- Updated progress tracking and sprint plan
- Added entry to active refactorings list

Rationale: Including UserOutput in CommandContext eliminates the need for
a separate create_default() wrapper function while keeping the valuable
report_error() utility. All commands now get a consistent UserOutput
instance from the context, reducing duplication and ensuring consistency.
