didericis-claude 9f65b137b9 feat(smolmachines): end-to-end launch + Bottle.exec + smoke + probes (PRD 0023 chunk 2d)

End-to-end launch flow for the smolmachines backend. Brings up
the per-bottle docker bridge + sidecar bundle, creates and
starts the smolvm guest pointed at the bundle's pinned IP via
TSI's `--allow-cidr <bundle-ip>/32`, yields a SmolmachinesBottle
handle that routes exec/cp through `smolvm machine exec / cp`,
tears everything down on context exit.

launch.py:
- ExitStack-managed: create_bundle_network → start_bundle →
  machine_create → machine_start (each registered for reverse
  teardown).
- daemons_csv="" for chunk 2d — bundle init logs "no daemons
  selected" and idles. Real daemon bringup with inner-Plan-driven
  env + volumes lands in chunk 4.

bottle.py:
- SmolmachinesBottle.exec → smolvm.machine_exec (captured).
- SmolmachinesBottle.exec_claude → direct subprocess.run with
  inherited TTY for interactive sessions.
- SmolmachinesBottle.cp_in → smolvm.machine_cp.

Architecture pivots forced by smolvm 0.8.0's CLI shape:
1. `--from <smolmachine>` and `--smolfile <toml>` are MUTUALLY
   EXCLUSIVE in smolvm 0.8.0. We need --from to avoid the
   registry-pull race that bit us on machine_start (libkrun
   agent's network attempt got refused by macOS with
   "connect: permission denied" on IPv6). So Smolfile is dropped
   entirely; per-bottle env + allow_cidrs flow as CLI flags
   (`--allow-cidr CIDR`, `-e K=V`) directly to machine_create.
2. `smolvm pack create --image` doesn't pull from the local
   docker daemon — only OCI registries via crane. The real
   claude-bottle:latest image lives in the local docker daemon
   and isn't reachable that way. Chunk 2d ships with an alpine
   placeholder; the agent-image-conversion gap belongs to
   chunk 4 (push the image to a registry, or smolvm grows a
   docker-daemon transport).

Other changes:
- machine_create grew `image=` / `from_path=` / `allow_cidrs=`
  / `env=` kwargs; smolfile= dropped.
- bottle_plan: smolfile_path → agent_from_path + guest_env.
- prepare: pack_create against `alpine:latest`, cached under
  ~/.cache/claude-bottle/smolmachines/ keyed by image ref.
- Deleted smolfile.py + test_smolfile.py (dead code now).

Tests:
- Unit: 540 passing (smolvm wrapper grew 4 new flag forms; one
  test renamed to reflect --from + --allow-cidr + -e combo).
- Integration: 3 new cases in tests/integration/
  test_smolmachines_launch.py, gated on Darwin + smolvm on PATH
  + docker + not GITEA_ACTIONS:
    * smoke: bottle.exec("echo hello-from-vm") round-trips with
      the correct stdout + returncode.
    * localhost-reach probe: agent dials 127.0.0.1:9 → connect
      refused (TSI's <bundle-ip>/32 allowlist doesn't include
      loopback). The regression test for the gap the PRD design
      pivot was about.
    * egress-port-bypass probe: agent dials <bundle-ip>:9099
      (egress's port) → connect refused. Chunk 2d has no
      daemons running so nothing's listening anyway; chunk 3
      will preserve this property once egress is up but bound
      to 127.0.0.1 inside the bundle.

End-to-end smoke + both probes green locally on macOS with
smolvm 0.8.0.

didericis 20f411b22e feat(smolmachines): backend skeleton + Smolfile/gvproxy renderers (PRD 0023 chunk 1)
test / unit (pull_request) Successful in 22s
test / integration (pull_request) Successful in 43s
Ships the smolmachines backend's prepare side: subpackage layout,
`_BACKENDS` registration under "smolmachines", preflight check
for `smolvm` + `gvproxy` on PATH, and the two config-file
renderers (Smolfile TOML + gvproxy YAML). Launch raises
NotImplementedError until chunk 2.

New module layout (mirrors backend/docker/):
  claude_bottle/backend/smolmachines/
    __init__.py            re-exports SmolmachinesBottleBackend
    backend.py             SmolmachinesBottleBackend façade
    bottle.py              SmolmachinesBottle stub (NotImpl until ch2)
    bottle_plan.py         SmolmachinesBottlePlan + .print()
    bottle_cleanup_plan.py SmolmachinesBottleCleanupPlan stub
    prepare.py             resolve_plan: writes both config files
    smolfile.py            TOML renderer (stdlib, no tomli_w dep)
    gvproxy_config.py      YAML renderer (same shape as pipelock_yaml)
    util.py                preflight + per-slug subnet + loopback port

The renderers are pure functions. `resolve_plan` runs the
preflight, allocates one host-side loopback port per active
sidecar (pipelock always; git-gate / supervise conditional),
derives a per-slug gvproxy subnet (hash-mod-254, skipping the
docker-default 17), and writes:

  - <stage>/gvproxy.yaml: subnet + DNS rule resolving only
    `proxy.internal` + port_forwards (one per active sidecar).
  - <stage>/smolfile.toml: guest command/env + virtio-net device
    backed by gvproxy's unixgram socket. No TSI flags — see
    PRD 0023 "Why gvproxy, not TSI".

The agent's HTTPS_PROXY etc. point at `proxy.internal:<gateway-
port>` so the guest dials through gvproxy. gvproxy resolves only
`proxy.internal` → the gateway IP, and forwards exactly the
listed ports to the host-side sidecar bundle (PRD 0024); every
other destination — host LAN, host loopback, public internet
directly — is unreachable by construction.

29 new unit tests covering renderer correctness, subnet
derivation stability + collision-avoidance, loopback port
allocation, and preflight error paths. Full unit suite: 532
passing.
