UniPlayer 0.3.0

• The AI assistant now receives a richer, explicit context message: media
  identity, playing or paused state, audio and subtitle tracks, the current
  line, a bounded window of recent dialogue, the selection and library
  metadata. Seeks and file changes cannot leave dialogue from a distant scene
  attached to the current one.
• Context-aware presets: What’s happening?, Who is this?, Explain this
  reference, Translate this line, Recap what just happened, Reviews &
  discussion, Is it worth continuing?, and Find similar in library. A preset
  appears only when the context needed to answer it exists.
• Reviews & discussion and Is it worth continuing? use DeepSeek Search with the
  configured DeepSeek key. Results include clickable sources, are bounded
  before they reach the model, and the prompt is spoiler-aware. Search is only
  offered for the HTTPS api.deepseek.com origin.
• The assistant can call a searchWeb tool. It requires an explicit Allow
  before spending a search, validates the query length, and rechecks the media
  and channel context around every asynchronous step.
• Settings now discloses DeepSeek Search data sharing and billing when that
  capability is available.
• The Simple/Advanced Settings fixes from the previous audit are included:
  hidden pages switch modes correctly, the outgoing mode keeps its remembered
  page, and expanded rows, ASS selections and accessory content survive a
  rebuild.
