The CLI was incorrectly reporting "some deployments failed" even when
deployments succeeded. This was because AllSucceeded() checked if every
response had StatusCompleted, but the Responses slice contains all
messages including intermediate ones like "started". Since started !=
completed, it returned false.
Now AllSucceeded() only examines final responses (using IsFinal()) and
checks that each host's final status is completed.

After a successful switch deployment, the listener now exits gracefully
so systemd can restart it with the new binary. This works together with
stopIfChanged/restartIfChanged to ensure deployments complete before
the service restarts.

- Add nixos-rebuild to listener service PATH in NixOS module
- Fix CLI deploy command hanging after receiving final status by properly
tracking lastResponse time and exiting when all hosts have responded

Reject NKey files that are readable by group or others (permissions
more permissive than 0600). This prevents accidental exposure of
private keys through overly permissive file permissions.

Implement the complete homelab-deploy system with three operational modes:
- Listener mode: Runs on NixOS hosts as a systemd service, subscribes to
NATS subjects with configurable templates, executes nixos-rebuild on
deployment requests with concurrency control
- MCP mode: MCP server exposing deploy, deploy_admin, and list_hosts
tools for AI assistants with tiered access control
- CLI mode: Manual deployment commands with subject alias support via
environment variables
Key components:
- internal/messages: Request/response types with validation
- internal/nats: Client wrapper with NKey authentication
- internal/deploy: Executor with timeout and lock for concurrency
- internal/listener: Subject template expansion and request handling
- internal/cli: Deploy logic with alias resolution
- internal/mcp: MCP server with mcp-go integration
- nixos/module.nix: NixOS module with hardened systemd service
