[BREAKING] Python: Update github-copilot-sdk integration to use ToolInvocation/ToolResult types (#4551)

* Update github_copilot package for github-copilot-sdk>=0.1.32 (#4549)

- Update requires-python from >=3.10 to >=3.11
- Remove Python 3.10 classifier
- Update mypy python_version to 3.11
- Update dependency to github-copilot-sdk>=0.1.32
- Fix ToolResult API: use snake_case kwargs (text_result_for_llm,
  result_type) instead of camelCase (textResultForLlm, resultType)
- Update test assertions to use attribute access on ToolResult
- Add ToolResult type assertions to tool handler tests

* Fix tests to use ToolInvocation dataclass instead of plain dict (#4549)

Update test_github_copilot_agent.py to pass ToolInvocation objects to tool
handlers instead of plain dicts, matching the github-copilot-sdk>=0.1.32 API
where ToolInvocation is a dataclass with an .arguments attribute.

* Add regression tests for ToolInvocation contract (#4549)

Add tests to lock in the new ToolInvocation-based calling convention:
- test_tool_handler_rejects_raw_dict_invocation: verifies passing a raw
  dict (old calling convention) raises TypeError/AttributeError
- test_tool_handler_with_empty_arguments: verifies ToolInvocation with
  empty arguments works correctly for no-arg tools

* Revert requires-python to >=3.10 to avoid breaking CI (#4549)

The repo CI runs with Python 3.10 (uv sync --all-packages) and all other
packages require >=3.10. Raising this package to >=3.11 would break the
shared install flow. The SDK dependency version constraint (>=0.1.32) will
enforce any Python version requirement from the SDK itself.

* Fix min Python version for github_copilot package to >=3.11

github-copilot-sdk>=0.1.32 requires Python>=3.11, which conflicts
with the package's declared >=3.10 minimum, breaking uv sync.

* Bump py version for GH workflows to 3.11, exclude GHCP sdk from 3.10 items

* Fix uv command

* Fixes

* Update samples
