Version packages: 0.16.0

[aaltshuler]

Release train for 0.16.0 (lockstep minor across the five packages): the settle camera + simulation presets and the fit zoom clamp — the first-load-feel pair. Changesets consumed; publish mode fires on merge.

Greptile Summary

This release-train PR consumes two changesets and advances all five Orbit packages to 0.16.0 while adding changelog entries for the fit-zoom clamp, settle-camera behavior, and simulation presets.

• Adds a demo harness and Playwright runner for comparing simulation configurations.
• Updates package versions and generated changelogs across the fixed release group.
• Removes the two consumed changeset files.

Confidence Score: 4/5

The package release metadata appears safe, but the new sweep runner should create its output directory before it is used.

The lockstep version changes and workspace dependency metadata are consistent; the concrete defect is isolated to the auxiliary sweep runner, whose documented default invocation aborts at its first screenshot when the destination directory is absent.

Files Needing Attention: apps/demo/run-sweep.mjs

Important Files Changed

Filename	Overview
apps/demo/run-sweep.mjs	Adds the automated simulation sweep, but its output directory is never created before screenshots are written.
apps/demo/src/sweep.tsx	Adds a query-configured graph fixture that exposes settlement and viewport metrics to the sweep runner.
apps/demo/sweep.html	Adds the Vite development entry page for the simulation sweep fixture.
packages/core/package.json	Advances the core package version to 0.16.0 consistently with the fixed release group.
packages/react/package.json	Advances the React package version to 0.16.0 while retaining workspace-based internal dependencies.
packages/engine-cosmos/package.json	Advances the Cosmos adapter version to 0.16.0 consistently with the release metadata.
packages/data/package.json	Advances the data package version to 0.16.0 consistently with lockstep versioning.
packages/omnigraph/package.json	Advances the Omnigraph package version to 0.16.0 consistently with lockstep versioning.

Missing output directory

When a developer uses a new output directory or the default sweep-out, the runner writes its first screenshot before creating that directory, causing the sweep to abort before producing measurements or its summary.

Suggested change

	const OUT = process.argv[2] ?? 'sweep-out';
	const OUT = process.argv[2] ?? 'sweep-out';
	await (await import('node:fs/promises')).mkdir(OUT, { recursive: true });
