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sustained use, exec-channel contention, no SIGWINCH) and is superseded by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.

The egress route fields table described `role` as a functional field
that wires built-in auth flows. PRD 0029 removed the
`claude_code_oauth` role; the manifest parser now rejects any `role`
value as reserved-for-future-use. Provider auth routes are injected
from `agent_provider.auth_token`.
- README: fix the `role` row to state it is reserved and any value is
rejected at load.
- examples/bottles/claude.md: the manual `api.anthropic.com` route used
the rejected `role` key and, even without it, would be silently
dropped (provider-injected routes win for a provisioned host) — so its
auth never took effect and the dlp comments described a route that
never exists in the plan. Replace it with the canonical
`agent_provider.auth_token` shape.

Pipelock was removed in PR #193. Update the five remaining places
where current documentation (README, examples/bottles/claude.md,
tests/README.md, docs/ci.md, sidecar_bundle.py comment) still
described the old pipelock + cred-proxy topology.
