feat(p2): Gondolin sandbox environments
A sandbox is a new env type (`type: "gondolin"`): a long-lived Gondolin micro-VM on an SSH environment, with
listed host folders and an HTTP(S) host allowlist. The worker reaches it over SSH to the host, where p2's launcher
(plugins/envs/sandbox: native, or Docker when the host's Node/QEMU are too old) runs pi-env's daemon inside the VM,
so tools, workspace, terminals, uploads and MCP work unchanged. Names outside the allowlist are refused before
the host resolves them.

Conversations working in a sandbox cannot leave it: location tools, subagent spawn/configure, AgentLocations.move,
the terminal tool, and one-shot agents (which now inherit their caller's own location) all keep them there; only the
owner's Relocate moves a session out, after a confirmation. conversationConfinement() exposes it to plugins.

Owner-only management in the Envs sheet: sandboxes listed under their host, host test reports sandbox support,
create/edit/start/stop/restart/test, lock icons in the top bar and sidebar. Tests in test/p2/sandboxes.test.ts
(real VM cases with P2_TEST_GONDOLIN=1) and ui-sandboxes.test.ts; docs in docs/remote-envs.md.
