[Feature]: Agent Onboarding

[ngaurav]

Feature Description

1. Create a start.md (which is common for all the agents)
   1. It will start with determining the type of agent (Coding/MCP-based/Custom SDKs) and have a single doc for the first two kind
2. Create individual docs pages for popular agents (Claude Code, hermes, Opencode,)
3. Cross references:
   1. Each individual doc page will have two sections (https://libretto.sh/docs/get-started/quickstart)
      1. Agent Prompt (refers to common start.md)
      2. Manual: It will contain some steps (but more importantly it will have a section for overriding default tools which will be different for each agent)
   2. Start.md should refer to manual docs (for just overriding section)

Use Case

So that users can easily setup webcmd with their harness of choice
