Poetry package listing fails for nested/non-root pyproject.toml projects (`poetry show` runs with wrong cwd)

Environment

• vscode-python-envs version: 1.36.0
• OS: Linux (devcontainer, linux-arm64)
• Poetry: 2.4.3

Description

When a Poetry project is registered via python-envs.pythonProjects but is not at the workspace root (e.g. a monorepo with scripts/pyproject.toml), the "Manage Packages" package listing fails with:

poetry: Poetry could not find a pyproject.toml file in <extension host cwd> or its parents

Root cause (found in source)

PoetryPackageManager.getDirectPackageNames() (src/managers/poetry/poetryPackageManager.ts) builds PoetryShowTopLevelCommand without ever passing a cwd:

const showTopLevelCmd = new PoetryShowTopLevelCommand({
    pythonExecutable: poetry,
    log: this.log,
});

This means poetry show --no-ansi --top-level always inherits the extension host process's own cwd (in a remote/devcontainer setup this is the vscode-server install directory), not the project directory. This is confirmed intentional by the existing unit test poetryPackageManager.unit.test.ts: "direct package listing inherits the process working directory" asserts runPoetryStub.firstCall.args[1] === undefined.

fetchPackagesFromTool() (used for plain poetry show --no-ansi) does compute a cwd via getPoetryCwd(), but that logic only reliably resolves when api.getPythonProjects() returns exactly one project. Since VS Code always implicitly adds the workspace root as a project (PythonProjectManagerImpl.getInitialProjects()), any repo with a registered non-root Poetry project (e.g. scripts/) ends up with 2+ projects, forcing the "match by environment identity" branch — which can return an empty matchingDirectories set (and thus undefined cwd) depending on how the workspace-root's own resolved environment compares.

Repro

1. Monorepo with pyproject.toml only in a subfolder, e.g. scripts/pyproject.toml.
2. Add to .vscode/settings.json:

   "python-envs.pythonProjects": [
     { "path": "scripts", "envManager": "ms-python.python:poetry", "packageManager": "ms-python.python:poetry" }
   ]
   

3. Open "Manage Packages" for the scripts project's Poetry environment.

Expected

poetry show commands run with cwd set to the registered project directory (scripts/).

Actual

Both poetry show --no-ansi --top-level and poetry show --no-ansi fail with "could not find a pyproject.toml", repeating every time packageWatchers triggers an auto-refresh.

Suggested fix

• Pass cwd (resolved from the project associated with environment, e.g. via api.getPythonProject(environment.environmentPath) or similar) into PoetryShowTopLevelCommand in getDirectPackageNames().
• In getPoetryCwd(), prefer resolving cwd from the actual project that owns the environment (e.g. via reverse lookup by environment path) rather than only matching by envId.id equality across all projects.

Inizia da src/managers/poetry/poetryPackageManager.ts, in particolare da getDirectPackageNames() e getPoetryCwd(), poi leggi poetryPackageManager.unit.test.ts e la relativa asserzione esistente sulla directory di lavoro del processo. Traccia come vengono risolti il progetto registrato e l’ambiente per i progetti annidati. Il lavoro è completato quando entrambi i comandi poetry show usano la directory del progetto registrato e gli unit test coprono questo comportamento di cwd.
