dtoro 9fc650fb12 web(sidebar): auto-expand folder tree ancestors of the active folder
When the timeline navigates to a nested folder (RightSidebar's
open-folder icon, URL hydration, back/forward), the LeftSidebar
already highlighted the matching row via filters.folderPath — but
if the parent folder was collapsed in the persisted openSet, the
highlighted row wasn't visible at all.

Each FolderTree instance now runs an effect that adds every
ancestor of the active path to its openSet on filter change. The
root instance expands the top-level ancestor first, which mounts
the next-depth FolderTree instance — and the same effect runs
there, cascading down to the leaf. Persisted to localStorage so
the expansion sticks across reloads.

Skipped in `readonly` mode (heap-convert picker has its own
selectedPath and shouldn't drive the sidebar state).

sv

Everything you need to build a Svelte project, powered by sv.

Creating a project

If you're seeing this, you've probably already done this step. Congrats!

# create a new project
npx sv create my-app

To recreate this project with the same configuration:

# recreate this project
npx sv@0.15.3 create --template minimal --types ts --install npm web

Developing

Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:

npm run dev

# or start the server and open the app in a new browser tab
npm run dev -- --open

Building

To create a production version of your app:

npm run build

You can preview the production build with npm run preview.

To deploy your app, you may need to install an adapter for your target environment.
