Alexander Brown cbdc7d030f feat: code splitting optimization - reduce initial bundle by 36% (#8542) ...

## Summary

Reduces initial module preload from 12.94 MB to 8.24 MB (-4.7 MB, -36%).

## Changes

- Split vendor chunks for better cache isolation (firebase, sentry,
i18n, zod, etc.)
- Exclude heavy optional chunks from initial preload: THREE.js, xterm,
tiptap, chart.js, yjs
- Lazy load 16 dialog components in dialogService
- Add \endor-yjs\ chunk for CRDT library

## Metrics

| Metric | Before | After |
|--------|--------|-------|
| Initial preload | 12.94 MB | 8.24 MB |
| vendor-other | 4,006 KB | 2,156 KB |
| dialogService | 1,860 KB | 1,304 KB |

All excluded chunks still load on-demand when their features are used.
