Juejin Usage 1.0.0 Rebuilt on Tauri: Smaller, Faster, and Cursor Login Fixed

Juejin Usage desktop client 1.0.0: rewritten based on Tauri, smaller installer, faster startup, lower memory usage.

New Tauri client, feature parity with original Electron version: local usage dashboard, tray, desktop pet, system notifications, account linking, and auto-update.
Uses the same application identifier as the original client, supports covering installation, preserves local data and login state.
Closing the window sends it to the tray; window position and system theme are automatically restored.
If the local service fails, auto-retry and show recovery status in the interface.

The old client (0.1.16) will prompt "Upgrade to new client"; click to automatically download and open the installer.
macOS: Drag the new app into "Applications" and replace the old one.
Windows: Complete the covering installation according to the wizard.

Fixed the issue where local subscription quota card and usage sync could not be read after the new Cursor encrypted login state: compatible with cursor-safe-storage ciphertext and old plaintext JWT (macOS keychain / Windows DPAPI / Linux peanuts keyring), and correctly displays Premium weekly quota.
Electron transitional version supports downloading and opening Tauri installer via remote switch (default off); official Tauri and Electron use the same app identifier.
Fixed heatmap last day cell, selection outline, and trailing month text clipping.
Unified desktop pet usage bubble time range, token, and cost label font size; widened pet popover, restored pet glow and pointer feedback.
Fixed stutter and jump when dragging pet size and animation speed sliders.
Reduced desktop artifact size: load actual used SVG components for subscription icons.
Fixed issue where Every Code cumulative usage might miss full usage when token written first and timestamp added later.
