Feature/rate limit

[Iamsdt]

This pull request introduces comprehensive documentation and configuration support for a new sliding-window rate limiting feature in the agent framework. It updates the README.md, agentflow.json, and skill template documentation to describe how to configure, enable, and extend rate limiting with memory or Redis backends, and clarifies optional dependency installation. Additionally, the pull request adds detailed documentation for new graph lifecycle hooks, providing guidance and examples for advanced orchestration-level callbacks.

Rate Limiting Feature and Documentation:

• Added a new rate_limit configuration block to agentflow.json and all relevant documentation, supporting sliding-window rate limiting with options for backend, request/window size, identity mode, and path exclusions. [1] [2] [3] [4]
• Updated installation instructions and documentation to clarify optional dependencies for Redis-based rate limiting, JWT auth, and media extraction, including pip extras syntax. [1] [2]
• Expanded the main feature list and guides in README.md and skill templates to include rate limiting, with references to new and existing documentation. [1] [2] [3] [4] [5] [6]

Graph Lifecycle Hooks Documentation:

• Added extensive documentation for new graph lifecycle hooks, including usage patterns, hook signatures, registration, and common use cases, to the callbacks and command reference.
• Updated the source map to reference new lifecycle hook fire points in the codebase, helping developers locate relevant implementation details.

These changes provide users with clear guidance on configuring and extending both rate limiting and advanced orchestration callbacks, improving both security and observability for agent-based applications.
