Delete the smolmachines backend (the whole bot_bottle/backend/smolmachines package and its tests). It had fatal Linux issues (TSI networking under sustained use, exec-channel contention, no SIGWINCH) and is superseded by the Firecracker backend (issue #342). Backend selection now: - default is macos-container on macOS, firecracker on KVM-capable Linux hosts, and docker as the last resort (was smolmachines). - firecracker is selected on a KVM host even when the `firecracker` binary isn't installed, so start routes through its preflight and prints an install pointer (same UX as require_container), instead of silently falling back. Split is_host_capable() (Linux + KVM) out of is_available() (adds the binary check) to drive this. Retarget the cross-backend tests (parity, print-parity, prepare, workspace, freezer, selection) from smolmachines to firecracker rather than dropping the coverage. Remove docker.util.image_id/save, which only smolmachines used. Update README/AGENTS/example bottles and stale comments; historical docs/prds are left as a point-in-time record. BREAKING: BOT_BOTTLE_BACKEND=smolmachines now errors as unknown. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WBMWTEtQdJ4W5UrWuLHCck
