Extract review pipeline MCP tools

[w1ne]

Summary

• Extract review/render pipeline MCP registry entries into src/agent/mcp/registry/reviewPipelineTools.ts.
• Keep TOOL_REGISTRY behavior and public order by spreading reviewPipelineToolEntries at the original tail position.
• Add a public contract assertion for the extracted review/render pipeline slice.

Moved tools

• review_cad
• review_paint_peek_latest
• design_loop
• flatten_pattern
• evaluate_sdf
• capture_animation
• render_preview

Review

• Subagent review: no findings. Reviewer confirmed moved entries preserve order, casts, schemas, handlers, public exports, and touched-file scope.

Verification

• Baseline focused MCP registry suite before edits: 7 files / 47 tests passed.
• TDD red: contract test failed on missing ./registry/reviewPipelineTools module.
• Contract test after extraction: 14/14 tests passed.
• Focused MCP registry suite after extraction: 7 files / 48 tests passed.
• npm run typecheck passed; only existing TanStack route warnings appeared.
• Touched-file ESLint passed.
• git diff --check passed.
• Mechanical block comparison: moved review/render block is byte-identical to the original tail block.
• No docs files changed.
