Format implementation steps correctly

Define ordered implementation steps with completion criteria

Documenting implementation roadmaps where step order, dependencies, and observable completion matter.

• · Step list: Title, Intent, Work, Done-when for each step

• · steps.md file with 5-15 ordered steps

Implementation roadmap defined; dependencies understood

• · Dependency ordering wrong
• · Too many steps (>15) or too few (<5)
• · Done-when criteria ambiguous

• · Explicit dependency ordering
• · Observable done-when conditions
• · Tests as first-class steps
