Fabro's Docker provider kind now maps onto the sandbox-driver Docker
provider instead of its own bollard implementation. Fabro keeps what is
its own: the clone decision and repository layout, the GitHub App push
credentials embedded in origin, git retry classification, the managed
labels that gate destructive operations, and the run-facing events.
- `clone.rs` performs fabro's clone over the driver `Git` and `Exec`
facets. An exact commit goes through the driver's pinned clone; a tag
pin runs fabro's init/fetch/attach sequence through `Exec` so the
fully qualified tag ref is the only revision consulted. Network
failures retry through `git_retry`, which now classifies driver errors
(exec output, provider retryability) and never replays an operation
whose outcome is unknown.
- `DriverSandbox` gains a pending-create state, a `RepoWorkspace` with
push-credential state, path resolution against the cloned working
directory, git lifecycle methods, image-pull progress mapped from
driver events, and an embedded terminal over the driver `Pty` facet.
- `docker.rs` builds the driver `SandboxSpec` (image, `/workspace`,
fabro labels, env, cpu/memory, network policy, run name) and attaches
by persisted container id, refusing containers without fabro's labels.
- Inventory, details, diagnostics, terminal, and reconnect run over the
driver: a `DriverInventoryProvider` lists by fabro's managed label and
projects `SandboxStatus` into fabro's inventory and details shapes.
- The bollard-based `docker.rs`, `provider/docker.rs`, Docker terminal,
Docker error variants, the `docker` cargo feature, and the bollard and
tar dependencies are gone. The Docker integration tests, the agent
shell test, the workflow artifact test, and the driver benchmark run
against the driver-backed sandbox.
