docs: correct CLAUDE.md CI claims and repoint to the mvp-* skill library

Root CLAUDE.md: state the actual CI pipeline (image builds + staging deploy
+ health checks; no tests, lint, or security scanning), replace root-level
npm commands with per-workspace equivalents, correct the OCR engine
description, rename Sprint Workflow to Issue Workflow (sprints unused), and
replace the retired agent-system references with the skill library entry
points. Remove emoji from Quality Standards per the project's own rule.
.claude/CLAUDE.md: rewrite as a pure index of the current .claude/ contents
with one row per mvp-* skill.
