v1.1.0 fixes various bugs found through improved testing.

Most importantly, it adds to the API an option to start a persistent sync server which speeds up subsequence calls to write_fig_sync, calc_fig_sync, etc.

LGTM — straightforward Renovate dependency bump.

Extended reasoning...

Overview

This PR bumps kaleido from 1.0.0 to 1.3.0 in template/requirements.txt. A single line change in the sandbox template requirements file.

Security risks

None. This is a version bump of a static image rendering library (kaleido is used with plotly to render figures to images). It does not touch auth, crypto, network handling, or any other sensitive code paths.

Level of scrutiny

Low. This is a mechanical, Renovate-generated dependency update touching only the sandbox template requirements.txt. The release notes describe internal refactors, a fix for a race condition on filename selection, a fix for hangs on large figures, and additive API changes (a new optional cancel_on_error argument). No breaking changes affect the typical write_fig/calc_fig usage that notebook users would invoke.

Other factors

The repo regularly accepts similar Renovate patch/minor bumps (see recent commits). The bug hunting system found no issues. No outstanding reviewer comments. Safe to shadow-approve.
