perf(list-table-v2): optimize resize performance with viewport-based observer management

- Observe miniTableRef instead of container to detect actual height changes
- Track height changes and skip re-probing when height unchanged
- Add IntersectionObserver to detach ResizeObserver for off-screen tables
- Add display:none (via .is-hidden class) for off-screen mini-tables
- Re-attach and remeasure when table becomes visible

Performance improvements:
- Window resize is now smooth with 14 tables on demo page
- Off-screen tables have no ResizeObserver overhead
- Mini-tables are fully removed from layout when off-screen

Also:
- Add oxlint as linting tool (replaces vue-cli-service lint)
- Add oxlintrc.json configuration
