Switch ReadwiseClient to @tauri-apps/plugin-http when running in
Tauri desktop mode, matching the pattern already used by WebDAV,
Hardcover, AI providers, translators, OPDS, and KOReader sync.
In a Tauri webview context the standard window.fetch is still subject
to CORS preflight rules and—on Android—the platform's cleartext-traffic
policy. @tauri-apps/plugin-http sends the request from the Rust side
via reqwest, bypassing the renderer entirely (no Origin header, no
preflight, no cleartext block). ReadwiseClient was one of the few
remaining services that had not yet adopted this transport, so users
on the desktop build could hit CORS or network errors when validating
tokens or pushing highlights.
