Python: [Bug]: poe syntax fails with FileNotFoundError for azurefunctions/pyproject.toml

[PratikWayase]

Description

What happened:
When running the uv run poe syntax command from the python directory, the workspace task script crashes with a FileNotFoundError. The script workspace_poe_tasks.py attempts to discover all workspace projects and tries to open packages/azurefunctions/pyproject.toml, but the file does not exist in the repository.

---

What did I expect to happen:
I expected the poe syntax command to successfully run formatting (fmt) and linting (lint) checks across all available workspace packages without crashing.

---

Steps to reproduce this issue:

Clone the repository and checkout the branch.
Navigate to the python directory: cd python
Ensure dependencies are installed (e.g., via uv sync).
Run the syntax command: uv run poe syntax

Agent analysis

Repro: discover_workspace_projects() in python/scripts/workspace_poe_tasks.py:149 calls load_toml() on every path returned by discover_projects() (in python/scripts/task_runner.py:35-60) without checking that pyproject.toml exists. Trigger: any subdirectory under packages/ that lacks a pyproject.toml (e.g., stale packages/azurefunctions/ left after the extraction in commit 4330901). Minimal repro: create an empty packages/azurefunctions/ directory and run uv run poe syntax from the python/ directory.

• Failing test: none
• Files examined: python/scripts/workspace_poe_tasks.py, python/scripts/task_runner.py, python/pyproject.toml
• Tests run: inline reproduction script confirming FileNotFoundError when packages/azurefunctions/ exists without pyproject.toml
• Reported version: 1.13.0
• Current version: 1.13.0

I can take this. I reproduced the discovery path from the report and plan to make the shared workspace project discovery ignore glob matches that do not contain a pyproject.toml, with a regression test covering a stale package directory. That keeps syntax and the other workspace task consumers consistent.
