James Stringer 4087baa4bf Add headless --headless daemon, HTTP/JSON API + Python SDK, and SSH key deploy
Headless mode: `appsandbox.exe --headless` runs a single-owner daemon that hosts
the core over a loopback HTTP/JSON API (http.sys) with a host.json discovery
file. A dependency-free Python SDK, examples, and a self-contained regression
suite live under tools/headless-api/ (PLAN.md = design rationale).

The API mirrors the GUI: create/start/shutdown/stop/delete/edit, snapshots and
branches (incl. base branches via the new asb_snap_base_branch_count), templates,
sshInfo, an SSE /v1/events stream, GUI-mirrored input validation, a startup
fail-fast (admin / Win11 build / VirtualMachinePlatform), and a single-instance
mutex shared with the GUI so only one of GUI/headless runs at a time.

SSH key deploy: sshDeployKey (requires sshEnabled) has the core generate an
AppSandbox ed25519 keypair once and the guest agent write the public key into
authorized_keys -- Windows administrators_authorized_keys (+ ACL), Linux/macOS
~/.ssh -- reporting a new ssh_key_deployed status (sshState 4). The GUI SSH
button and the SDK use the key for password-less login. Verified end-to-end on
Windows.

The Linux guest builds its agent/driver source from this branch's GitHub repo;
asb_core.c points the prefetch at "headless-api" (revert to "main" before merge,
see PLAN.md).
