feat(vite): summarize production builds

[lntutor]

Summary

• add rtk vite build routing for direct, npx, npm exec, and pnpm Vite invocations
• summarize successful asset tables with module count, total raw/gzip size, build time, and the five largest assets
• preserve Rollup/plugin warning text and complete failure output, with --full and watch-mode passthrough
• automatically reuse the Vite formatter when rtk npm run build output identifies Vite

Verification

• cargo fmt --all -- --check
• cargo clippy --all-targets --all-features -- -D warnings
• cargo test --all-features (2,505 passed, 8 ignored)
• cargo build --release --all-features
• controlled live success, --full, exit-2 failure, and npm-wrapper runs
• synthetic 100-asset table verifies at least 75% output reduction

Closes #2744

The benchmark failure is unrelated to this change: mockhttp.org/json/1 rotates response payloads, while the benchmark compares two separate requests. I reproduced the same failure mode on develop and opened #3340 to make the curl JSON comparison deterministic with the repository fixture. All other checks on this PR pass.
