fix(server): load Jude OpenCode subscription models from the right config

[digitalbase]

OpenCode in Jude could miss models supplied by Anthropic and Codex subscriptions because its inventory commands inherited the backend process directory instead of using the configured server working directory. That allowed OpenCode to resolve a different project config and plugin set.

The inventory path now carries the server cwd through to both opencode models --verbose and opencode agent list, with regression coverage that verifies model discovery stays anchored to that directory.

Tests: vp test run apps/server/src/provider/Layers/OpenCodeProvider.test.ts apps/server/src/provider/opencodeRuntime.cliParsers.test.ts; vp run --filter t3 typecheck

Model: GPT-5
Harness: Codex desktop
