v0.3.2

✨ Feature

• Added richer admin conversation logs with upstream, model route, protocol, binding code, usage, and tool details.

⚡ Optimization

• Improved the Files page and preview experience across PDF, sheets, documents, media, images, text, and code, including loading, zoom, fullscreen, and detail views.
• Standardized workspace and sidebar navigation across recent conversations, projects, starred items, search, sharing, exporting, deletion, and bulk actions.
• Improved chat generation state handling for long streams, retry/edit branches, pending messages, and concurrent generation limits.
• Improved billing settings wording by changing prepaid amount into a clearer per-request reservation concept.

🐛 Fixed

• Fixed usage settlement when the final bill exceeds available balance, so completed paid requests are still recorded and settled correctly.
• Fixed duplicate or retried billing settlement from creating repeated charges for the same usage request.
• Fixed paid generation cancellation/failure paths to release, renew, or mark billing reservations for reconciliation correctly.
• Fixed hardcoded branding across sidebar, login, screenshots, notifications, generated media placeholders, and public-facing views.
• Fixed MinerU file type support, presentation document handling, and related MIME guidance.
• Fixed unstable dialog content during close animations across admin, settings, files, recent, Skills, and Prompt views.
