Greptile Summary

Routine dependabot patch upgrade of svelte from 5.55.1 to 5.56.4, pulling in several bugfix releases (reactivity context fix, searchParams notification accuracy, optional-parameter stripping in TypeScript scripts, etc.).

• package.json updated the svelte devDependency specifier; package-lock.json regenerated with updated transitive deps (@sveltejs/acorn-typescript 1.0.10, devalue 5.8.1, esrap 2.2.12).
• esrap reclassified @typescript-eslint/types from a regular dependency to an optional peer dependency, reducing the install footprint — this is safe since esrap is a dev-only Svelte compiler utility.
• The lock file also reflects the project version as 0.14.10 (up from 0.14.9 in the previous lock), consistent with the package.json already being at that version on main.

Confidence Score: 5/5

Safe to merge — only patch-level Svelte bugfixes and their transitive dep updates, no API or behavioral changes relevant to this app.

All changes are confined to devDependencies (Svelte is compile-time only in this Tauri app). The 5.55.1 → 5.56.4 range covers four patch releases that exclusively fix bugs in the compiler/reactivity system. No breaking changes were introduced; the Dependabot compatibility badge shows a high compatibility score. The esrap peer-dep restructuring reduces install overhead without affecting runtime behavior.

No files require special attention.

package-lock.json	Lock file regenerated: svelte 5.56.4, acorn-typescript 1.0.10, devalue 5.8.1, esrap 2.2.12 (with @typescript-eslint/types moved from hard dep to optional peer dep); project version reflected as 0.14.10.
