feat: add README Generator agent

[jbkun069]

What does this PR do?

Adds a new readme-generator agent that creates clean, professional, and developer-friendly README.md files. It takes a repository URL, project description, tech stack, and desired sections as inputs to automatically generate copy-pasteable documentation.

Type of change

• New agent
• Bug fix
• UI improvement
• Docs update
• Something else (describe below)

Checklist

For every PR:

• I was assigned to this issue before starting
• I have read CONTRIBUTING.md
• This PR is linked to issue [Agent]: README Generator #148
• I tested this locally with npm run dev
• No API keys are anywhere in my code
• I did not add any new packages without discussing it first

For new agent PRs:

• I tested the agent with a real API key
• I created a new file in src/agents/definitions/ with the agent config
• The agent id is lowercase and uses kebab-case (like my-agent-name)
• The icon name is from [lucide.dev/icons](https://lucide.dev/icons)
• The system prompt clearly describes the format of the output
• This agent is not a duplicate of one that already exists

Anything else I should know?

The agent is configured to use claude-sonnet-4-6 via Anthropic as its default provider, though it supports any provider. The system prompt is heavily optimized to output valid GitHub-flavored Markdown without conversational filler so it can be directly copied into a repository.
