feat(*): Easier for a new user/developer to use

[KevinHuSh]

Problem

1. TUI is advanced. If a GUI is provided, the bar of user will be reduced.
   Like OpenClaw/CherryStudio, a control UI(a WEB UI) is very friendly for a user/developer.
   So, the items in ~/.raven/config.json should be configured via a control UI.

   • LLM provider and model
   • A local working directory
   • MCP servers
   • Chat channels
   • EverOS long-term memory
   • Deep Research
   • Sandbox or execution location

2. Terminal installation is advanced. If a docker image is provided, a lot of exceptions will be avoided.
   An indepenent experimental eviroment is crucial for a developer. It's really nice for us to provide one.

3. What about adding a benchmark(borwseComp) for local file search/digestion.
   The deep research is porvided as a third-party service invocation tool. A good local files(MD/TXT) content deep understandig is also very useful.
