v1.12.0

compare changes

Features

• Add ErrorBoundary and VizErrorBoundary components (Vue defineComponent) with ErrorFallback.vue for graceful error display
• Add mermaid FOUC prevention: CSS visibility: hidden + data-mermaid-status lifecycle + Apple HIG shimmer placeholder (dark/light mode)
• Add stale chunk auto-reload handler for deploy version skew (SPA navigation resilience)
• Add verify-skip info-string flag for code blocks that should not be compiled

Performance

• Rewrite verify-code-blocks.ts execution engine (~30x faster: 115s → 3.6s)
  • TypeScript: single ts.createProgram with per-block module isolation
  • Rust: rustc --emit=metadata (skip codegen+linking) + bounded concurrency
  • Go: shared module + single go vet ./...
  • Python: bounded-concurrency py_compile

Fixes

• Fix <p> nesting hydration warning in docs/index.md
• Fix Rust answer for batch-processing pattern exercise
• Unify approximate year notation in zh timeline table (约 → ~, ~1960s → ~1960)
• Downgrade mermaid render failure log from console.error to console.warn

CI/CD

• Split verify-code into dedicated CI job with all 4 toolchains — fixes historical gap where 138 non-TS code blocks were silently skipped in CI
• Fix Go cache warnings (use go.mod instead of non-existent go.sum)
• Script now fails hard in CI (CI=true) when a toolchain is missing

Documentation

• Expand SOP 08 AI Agent Review from 2 to 7 specialized roles (Contributor, Content, Source Proof, Multi-Language, Bilingual, Security, Frontend & A11y)
• Add prerequisites table to CONTRIBUTING.md and CONTRIBUTING.zh-CN.md
