Charles Bochet 159bb9d70a A few fixes on table performance (#18304) 
## RecordTable Performance Investigation & Optimization (WIP)

Investigates what makes the RecordTable slow (14 components, ~12 hooks
per cell) and starts applying fixes.

### Key Findings (2,000 cells benchmark)

![Cell Render
Benchmark](https://github.com/twentyhq/twenty/blob/table-perf/packages/twenty-front/src/modules/object-record/record-table/__perf__/cell-render-benchmark.png?raw=true)

![State Access
Benchmark](https://github.com/twentyhq/twenty/blob/table-perf/packages/twenty-front/src/modules/object-record/record-table/__perf__/state-access-benchmark.png?raw=true)

- **Jotai atoms are the dominant cost**: 10 atom reads/cell = +312%.
Full sim with atoms = +476%.
- **Derived atoms are 3x cheaper** than individual reads (12 sources:
+93% vs +294%).
- **Component depth is expensive**: 4-level nesting = +82%, 14 wrappers
= +109%.
- **Styling engines are comparable**: Linaria vs Emotion is within
noise.
- **Context reads and useState are nearly free** vs baseline.

### Optimizations Applied

1. **Static focus providers** — replaced per-cell `useState(false)` with
static context. Eliminates 400 useState instances.
2. **Delegated onMouseMove** — single handler on table body instead of
400 per-cell handlers.
3. **Hoisted `useObjectMetadataItems()`** — moved from per-cell to
table-level context. Eliminates 400 global atom reads.

### Tooling

- Perf page at `/__perf__/table`: 17 cell render + 13 state access
benchmarks
- Render profiler: `window.__RECORD_TABLE_PROFILE = true`
- Full plan in `__perf__/PERFORMANCE_PLAN.md`

### Remaining Phases (not high priority to-be-honest)

| Phase | What | Status |
|-------|------|--------|
| 1 | Separate display from interaction | Partial |
| 2 | Flatten hierarchy (14 → ~5 components/cell) | TODO |
| 3 | Reduce atom reads per cell | Partial |
| 4 | CSS-only hover/focus | TODO |
| 5 | Event delegation, lazy Draggable | TODO |
