Christian Byrne b3c939ff15 fix: add Safari requestIdleCallback polyfill (#5664)
## Summary

Implemented cross-browser requestIdleCallback polyfill to fix Safari
crashes during graph initialization.

## Changes

- **What**: Added
[requestIdleCallback](https://developer.mozilla.org/en-US/docs/Web/API/Window/requestIdleCallback)
polyfill following [VS Code's
pattern](https://github.com/microsoft/vscode/blob/main/src/vs/base/common/async.ts)
with setTimeout fallback for Safari
- **Breaking**: None - maintains existing GraphView behavior

## Review Focus

Safari compatibility testing and timeout handling in the 15ms fallback
window. Verify that initialization tasks (keybindings, server config,
model loading) still execute properly on Safari iOS.
