**MVP umbrella concept cleanup for v1.50.0-canary.2** — adds the seven MVP-related domain terms (MVP Mode, User Story, Walking Skeleton, Vertical Slice, Behavior-Adding Task, MVP+TDD Gate, SPIDR Splitting) to `CONTEXT.md` so the project's domain glossary is consistent with the shipped surface; adds `references/mvp-concepts.md` as a single index for the six MVP reference files (planner-mvp-mode, skeleton-template, user-story-template, spidr-splitting, execute-mvp-tdd, verify-mvp-mode); clarifies the `--mvp` + `--prd` interaction in the plan-phase Walking Skeleton block. No behavior change.
