[WIP] Update configuration for Python 3.10 and extension bundle

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

Problem: The Functions host fails locally because host.json references extension bundle v1.8.1 which is below the Functions runtime minimum (2.6.1+). The project also indicates Python 3.8/3.9 in setup instructions but modern Azure Functions requires Python 3.10+ (and the user's Azure environment currently supports 3.10 as the minimum). We need to update configuration files so the project runs locally and deploys on Azure using Python 3.10.

Scope: Make minimal, safe changes to the repository to target Python 3.10 and fix the extension bundle error. Changes to include:

1. host.json: Update extensionBundle.version to a range that enforces the minimum required by the Functions runtime, e.g. "[2.6.1, 3.0.0)". Keep existing logging configuration intact.

2. Pipfile: Update the [requires] python_version to "3.10". If Pipfile does not exist or does not have requires, add it accordingly. Do not modify dependency entries unless necessary.

3. Add runtime.txt at repository root with a pinned Python 3.10 micro version (python-3.10.12) to help Azure/Oryx build choose 3.10 during deployments.

4. Provide clear commit message, create a feature branch (e.g. "update/python-3.10-host-config"), and open a pull request describing the change and why it is needed. Include testing notes: run pipenv --python 3.10 && pipenv install (or create a 3.10 venv), python --version should be 3.10.x, and func start should no longer fail due to extension bundle version.

Files to create/modify (exact content must be provided):

• host.json: update extensionBundle.version to "[2.6.1, 3.0.0)" while preserving other keys.
• Pipfile: set python_version = "3.10" under [requires]. If file exists, modify only that field; otherwise create a minimal Pipfile with project dependencies preserved if possible.
• runtime.txt: single line python-3.10.12.

Do not change source code files or requirements.txt in this PR. Keep changes focused on configuration that ensures local runtime compatibility and a smooth Azure deployment path.

Create a branch, commit the changes, push to the repo, and open a pull request with a descriptive title and body explaining the motivation, changes, and local verification steps. Include the new/updated file contents in the PR description.

Please proceed to implement these changes and open the PR in the repository.
