feat(rust): port ci queue-info to native Rust

[jd]

The Rust binary now serves mergify ci queue-info natively.
The Python implementation (mergify_cli/ci/cli.py:queue_info)
and its tests are removed in the same PR — port-and-delete keeps
a single live copy.

The previous commit landed a live-smoke test pinning the
INVALID_STATE exit code outside an MQ context. That same
test now exercises the Rust path.

ci queue-info prints the merge-queue batch metadata embedded
in the current draft PR as pretty JSON. Outside an MQ context
(no event payload, no PR body fenced block) it exits
INVALID_STATE (exit 7).

When $GITHUB_OUTPUT is set (GitHub Actions runner), the
command also appends the metadata as queue_metadata under a
random ghadelimiter_<uuid> heredoc, matching the pattern
GitHub Actions expects for multi-line workflow outputs.

The implementation reuses the shared queue_metadata and
github_event modules introduced by the previous (git-refs)
port commit.

Adds the uuid dep (v4 random UUIDs for the ghadelimiter) to
the mergify-ci crate.

3 new queue-info tests in the mergify-ci crate. The Python
queue-info tests in test_cli.py, test_cli_exit_codes.py,
and test_exit_code_contract.py are removed.

Pull request overview

Ports mergify ci queue-info from the Python CLI into the Rust-native mergify binary, removing the legacy Python implementation and migrating coverage to Rust while preserving the INVALID_STATE (7) contract outside merge-queue context.

Changes:

• Add Rust-native ci queue-info subcommand wiring in the Rust CLI entrypoint.
• Implement queue-info in mergify-ci (pretty JSON + optional $GITHUB_OUTPUT heredoc output).
• Remove the Python queue-info implementation and its Python-unit tests in favor of Rust tests (while keeping the live smoke/contract test elsewhere).
