* docs(guides): add performance guide and preview-stutter troubleshooting
Adds a dedicated Performance guide covering preview-vs-render cost model,
expensive CSS patterns (backdrop-filter, filter, shadows), image sizing,
and how to diagnose slow compositions with Chrome DevTools.
Cross-links from troubleshooting (new "Preview stutters" accordion) and
common-mistakes (new "Oversized source images" and "Heavy backdrop-filter
stacks" accordions). Wires the new page into docs.json nav.
Also fixes a pre-commit format hook edge case: oxfmt would exit 2 when
the only staged files matching the format glob were all covered by
.prettierignore (e.g. docs-only changes). Add --no-error-on-unmatched-pattern
to the lefthook oxfmt invocation so docs-only commits are not blocked.

* docs: call out preview performance limits at the entry points
The preview command, studio package, and determinism concept pages all
frame preview as visually equivalent to render — correct for fidelity,
misleading for playback smoothness. A user who reads those pages and
then hits a paint-heavy composition has no way to know why preview
stutters, short of drilling into troubleshooting.
Adds short notes at each entry point linking out to the new Performance
guide, so users hit the "preview is hardware-bound, render isn't"
explanation wherever they land first.
