Saved state fixtures (state.json as the desktop host reads it), used by
  - src-tauri/tests/state.rs: migration of every old format to the current one
  - tools/desktop-boot-check.ts: the built window booted against each, with a mocked host and the real sidecar
@EXAMPLES@ is replaced with the repo's examples/ folder (folders that exist); /nonexistent/... folders are missing.
empty.json               no file content yet (fresh install)
d1-missing-folders.json  desktop D1 format (projects + accounts only, no version) with two folders that are gone
d3-full.json             D3 format without version: studios, accounts in studios, overrides, settings, one folder
                         that exists and one that is gone
shared-profiles.json     0.8 format: accounts name their credential profile (~/.storebound/credentials, shared with
                         the CLI); the apple account comes from a profile the CLI wrote; the folder pins storebound 0.6.0
The .host.json answers come after the start-up sync: D1's accounts have no keychain entry (they stay without a
profile), D3's keychain entries move into credential profiles.
