feat(gateway): add elevated gateway info

[elezar]

Summary

Add an elevated gateway info surface for live runtime metadata, including the initialized compute driver name and driver-reported capability snapshot.

openshell status remains aligned with main: it uses the existing Health RPC and HTTP fallback behavior. Runtime driver details are exposed through openshell gateway info, backed by the admin-gated GetGatewayInfo RPC.

This also moves the old local registration metadata formerly shown by openshell gateway info into openshell gateway list / openshell gateway list -o json.

Related Issue

None.

Related PRs

• feat(cli): add --output json/yaml to sandbox get, status, and sandbox create #1989 adds JSON/YAML output for openshell status as part of broader CLI structured-output work. This PR no longer changes openshell status output.

Changes

• Folded local gateway registration metadata into openshell gateway list, including is_remote, remote_host, and resolved_host in structured output.
• Added GetGatewayInfo with gateway version, service status, and initialized compute driver info.
• Snapshot driver identity/version during compute runtime initialization and return it from the new admin-authenticated RPC.
• Added openshell gateway info -o table|json|yaml.
• Restored openshell status to the behavior present on main.
• Updated gateway docs and compute runtime architecture notes.

Breaking Change

openshell gateway info no longer shows local gateway registration metadata. Use openshell gateway list or openshell gateway list -o json for local registration details.

Previous behavior from the globally installed openshell 0.0.75 CLI:

/home/elezar/.nix-profile/bin/openshell gateway info

Gateway Info

  Gateway: info-dev
  Gateway endpoint: http://127.0.0.1:19080

Testing

• mise run pre-commit passes
• Unit tests added/updated
• E2E tests added/updated (if applicable)

Attempted devenv shell -- mise --cd /home/elezar/dev/OpenShell run pre-commit through the host devenv at ~/.dotfiles/devenvs/openshell; it fails in this environment due to:

• helm:lint: chart metadata missing dependency postgresql
• rust:check/rust:lint: sqlx_macros dynamic library requires GLIBC_2.39
• test:rust: openshell-supervisor-network process identity shared-socket test failed

Additional checks run:

• nix develop -c cargo fmt --check
• nix develop -c cargo test -p openshell-cli gateway_list
• nix develop -c cargo test -p openshell-cli info
• git diff --check origin/main..HEAD

Manual smoke check against a branch-local Docker gateway:

target/debug/openshell gateway info -o json

{
  "auth": null,
  "compute_drivers": [
    {
      "capabilities": {
        "driver_name": "docker",
        "driver_version": "29.2.1"
      },
      "name": "docker"
    }
  ],
  "gateway": "info-dev",
  "server": "http://127.0.0.1:19080",
  "status": "healthy",
  "version": "0.0.80-dev.7+g8fb2782a"
}

Example local registration metadata output:

target/debug/openshell gateway list

  NAME       ENDPOINT                 TYPE   SOURCE  AUTH
* info-dev   http://127.0.0.1:19080   local  user    plaintext
  openshell  https://127.0.0.1:17670  local  user    mtls

target/debug/openshell gateway list -o json

[
  {
    "active": true,
    "auth": "plaintext",
    "endpoint": "http://127.0.0.1:19080",
    "is_remote": false,
    "name": "info-dev",
    "remote_host": null,
    "resolved_host": null,
    "source": "user",
    "type": "local"
  },
  {
    "active": false,
    "auth": "mtls",
    "endpoint": "https://127.0.0.1:17670",
    "is_remote": false,
    "name": "openshell",
    "remote_host": null,
    "resolved_host": null,
    "source": "user",
    "type": "local"
  }
]
