📝 Walkthrough

Walkthrough

This PR introduces a complete Rust agent application that discovers system tools, collects host information, and sends periodic heartbeats to a configured server. It includes CLI configuration, local task execution handlers, and HTTP heartbeat functionality with proper error handling and logging.

Changes

Cohort / File(s)	Summary
Infrastructure & Build .github/workflows/ci.yml, .gitignore, Cargo.toml	Added GitHub Actions CI workflow (build, test, clippy on main/claude/* and PRs), updated .gitignore to exclude /target, and defined Rust project manifest with dependencies for async execution, HTTP, serialization, logging, and CLI parsing.
Configuration Management src/config.rs	Added CLI argument parser struct supporting environment variables and defaults, with agent ID auto-generation via UUID when unspecified.
System Discovery src/discovery.rs	Added tool discovery by probing installed executables for version info and host information collection (hostname, OS, optional IP).
Task Execution src/executor.rs	Added task dispatcher supporting four built-in handlers: service restart, HTTP requests, numeric condition evaluation, and duration-bounded waits, with execution timing and error capture.
Server Communication src/heartbeat.rs	Added HTTP client for sending agent heartbeat payloads (identity, host info, tools) to a configured server with bearer authentication and error handling.
Application Entry src/main.rs	Added async main entry point wiring configuration, logging, discovery, and an infinite heartbeat loop with periodic retry and sleep intervals.

Poem

🐰 Hop, hop, heartbeat goes the bouncing friend,
Tools discovered, host info to send,
Tasks executed with restarts and waits,
A new agent emerges to automate fates! 🐇✨
