- Remove hardcoded --backend=macos-container flag reference in
firecracker/util.py require_firecracker() error message
- Remove --backend flag from cli.py start; backend selection now
driven exclusively by BOT_BOTTLE_BACKEND env var or auto-selection
- Skip unavailable backends in cli.py cleanup (fixes crash on Linux
when macos-container.prepare_cleanup calls require_container())
- Add two-tier auto-selection: VM backend first (macos-container on
macOS, firecracker on Linux+KVM); fall back to docker with a
security warning and interactive i/d/q prompt; exit if docker
also unavailable and print VM install instructions
Closes#344
Cover the new production lines added on this branch:
- cli/__init__: MissingEnvVarError maps to return 1
- cli/start: no-agents-defined path, prepare_with_preflight calls
render_preflight, _text_render_preflight backend name output
- env: resolve_env raises MissingEnvVarError for missing interpolated var
- smolmachines/launch: _proxy_host Linux/non-Linux branches,
_discover_urls git-gate host and supervise URL stamping

`--headless` is a non-interactive launch path for `cli.py start`:
agent, bottles, label, and color come from flags + manifest defaults
with no TUI selectors and no y/N preflight (auto-confirmed via a new
`assume_yes` param threaded into the shared `_launch_bottle` core).
- `--bottle` (repeatable) defaults to the agent's own `bottle:`;
`--label` defaults to the agent name and auto-uniquifies on slug
collision; `--color` defaults to none.
- `--prompt TEXT` is required in headless mode and is delivered to the
agent via a new `headless_prompt(prompt)` method on `AgentProvider`,
implemented for claude (`-p`), codex (positional), and pi (`-p`).
- The agent still execs on inherited stdio/PTY, so whatever allocates
the PTY drives the live session; only the launch chrome is headless.
- `--headless --dry-run` previews the resolved plan without launching.
Adds unit coverage in tests/unit/test_cli_start_headless.py and
headless_prompt tests for each provider. Also stubs headless_prompt on
the in-test AgentProvider subclasses so the unit suite collects cleanly.
Closes#315.
