Add WebSpeech/browser ASR support on windows
thx to @olerty !

Add MIT License to the project

release: finalize ClassFox v1.2.0 polish

feat: improve monitoring flow and docs

feat: real-time transcript with in-place line update & update docs

- Transcript now updates live: each ASR callback overwrites the active
  line (seek + truncate), so LLM always sees the latest text
- Sentence boundary (。？！；) finalizes the line, starts a new active line
- Keyword detection still uses delta-only to prevent repeated alerts
- On stop, flush remaining active line to transcript
- Update README: add keywords.txt in usage flow and project structure
- Update 开发指南: add transcript strategy docs, keyword config section,
  and changelog entries for DLL fix / keyword file / real-time transcript
