Fixes for week 1 examples

[pamelafox]

Purpose

This PR will include fixes needed to get Week 1 examples working locally and in Codespaces.
This will be updated after all examples are verified.

[pamelafox]

All examples run except workflow examples that are out-of-date and are fixed in subsequent PRs, so am removing from main for now.

Pull request overview

This PR aims to make the Week 1 examples work locally and in Codespaces by adjusting dependencies and the devcontainer build environment, but it also removes several workflow example scripts that are referenced in documentation.

Changes:

• Updated agent-framework-* git dependency pins and enabled uv prerelease resolution.
• Updated the devcontainer image to install Rust tooling for building Rust-based Python dependencies.
• Removed three workflow example scripts (workflow_basic.py, workflow_hitl.py, workflow_magenticone.py).

examples/workflow_basic.py:1

• This example script is being deleted, but it is still referenced from README.md (and there are Spanish equivalents under examples/spanish). That will leave broken links and removes a Week 1 workflow example rather than fixing it. Either restore/update this example (preferred if Week 1 expects it) or update the docs/example index to reflect the removal/move.
  examples/workflow_hitl.py:1
• This example script is being deleted, but it is still referenced from README.md (and there are Spanish equivalents under examples/spanish). That will leave broken links and removes the HITL workflow example rather than fixing it. Either restore/update this example or update the documentation/example listing to match the new location/removal.
  examples/workflow_magenticone.py:1
• This example script is being deleted, but it is still referenced from README.md (and there are Spanish equivalents under examples/spanish). That will leave broken links and removes the MagenticOne workflow example rather than fixing it. Either restore/update this example or update the documentation/example listing to match the new location/removal.
  .devcontainer/Dockerfile:9
• The curl https://sh.rustup.rs | sh pattern executes a remote installer script from sh.rustup.rs with root privileges during the devcontainer build without any integrity verification or pinning. If the remote endpoint or its supply chain were compromised, this would give an attacker arbitrary code execution in developer environments and the ability to tamper with tools or checked-out source. Prefer installing Rust via a distribution package or a pinned, checksummed installer/image instead of executing a mutable remote script at build time.

RUN curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
