Initialize agentd repository with Cargo workspace and project structure

[pentaxis93]

Context

agentd is an open-source autonomous AI agent runtime. "Run autonomous AI agents
on your own infrastructure." Unix daemon convention (like sshd, containerd).

This is the first commit. Everything downstream depends on this structure being
right.

Requirements

Create the following workspace structure (LICENSE already exists in the repo):

agentd/
├── Cargo.toml                  # Workspace root
├── LICENSE                     # Already exists — do not modify
├── README.md                   # See spec below
├── AGENTS.md                   # Stub: "See issue #2"
├── ARCHITECTURE.md             # Stub: "See issue #3"
├── crates/
│   ├── agentd/                 # Main binary
│   │   ├── Cargo.toml
│   │   └── src/

README.md spec

The README must communicate in one screen:

• What this is (agent runtime daemon)
• What it does (run autonomous AI agents on your own infrastructure)
• Current status (early development, not yet functional)

No philosophy. No backstory. No clever metaphors. Technical and direct.

Include sections:

• One-paragraph description
• Status badge area (placeholder)
• Architecture overview (one paragraph pointing to ARCHITECTURE.md)
• Quick start (placeholder: "Coming soon")
• License

Cargo workspace

• Edition 2024
• Rust version 1.85+
• Workspace-level dependency management
• All crates start at version 0.1.0

Verification

• cargo build succeeds with no warnings
• cargo test passes (even if no tests yet)
• cargo clippy clean
• README renders correctly on GitHub
