feat: enhance after-pack script to copy OpenClaw runtime dependencies

- Added a new script `bundle-openclaw.mjs` to bundle OpenClaw runtime dependencies.
- Updated `after-pack.cjs` to copy bundled OpenClaw runtime and its node_modules.
- Improved cleanup of unnecessary development files in node_modules.
- Adjusted paths for resources in the packaging process.

style: update loading indicator styles in ChatHistoryPanel

- Changed the border radius and padding for the loading indicator in ChatHistoryPanel.

fix: improve ProvidersSection to handle provider account syncing

- Added logic to sync model configuration to provider accounts.
- Introduced error handling and loading states during the sync process.
- Enhanced vendor resolution and account management logic.
