fix(sandbox): Celesto maps every status and warns before dropping a stopped disk - #45

Conversation
The status map left out `restorable`, which Celesto reports after a spot interruption before it restores the sandbox on another host, and `pending`, which its SDK waits through on create. Both now map to `starting`, so the sweep leaves the record alone and a start keeps waiting instead of falling through to an untracked state. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Celesto's pricing page says stopped root disks are kept for 30 days, and the driver already reads `disk_delete_at` to report an expired sandbox. Declaring `diskRetentionDays` lets the Sandboxes list and the settle prompt warn before that happens, as they do for Boat. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Celesto's create takes no name, label, or project, so its sandboxes cannot carry the host tag that orphan detection needs. Its persistent home is refused on the coding-agent template, so a spot move may lose T3's state. Say both where the driver contract and lifecycle describe Celesto, and note the refused field beside the create body. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Problem
The Celesto driver lagged Boat's: statuses the API reports (
restorable,pending) were unknown to it, the Sandboxes list never warned before Celesto drops a stopped disk, and the driver docs did not say which Boat capabilities Celesto cannot offer.Change
Read against Celesto's own API client (Python package 0.1.13, generated from its API spec) and the TS SDK 0.1.6:
restorable(a spot move in progress) andpending(create) map tostarting, so the sweep leaves those records alone.info.diskRetentionDaysis 30, from celesto.ai/pricing ("Stopped root disks are retained free for 30 days").external_volume_enabled(persistent home) is refused on thecoding-agenttemplate with a 422. A comment beside the create body says so, so the field is not re-added.Desktop and templates are not part of this PR: the fork shows no Boat desktop today, and Celesto templates are built from a build script rather than saved from a machine.
