[pull] master from DataDog:master - #466

* Fix broken logo in Sanity dashboard, use official Druids URL

* Move sizing to contain to avoid stretching the logo

* Add _get_package_dir utility method to AgentCheck

Add a _get_package_dir() method to AgentCheck that resolves the filesystem
path of the concrete check subclass's package directory. This enables base
class methods to locate data files shipped alongside integration code.

The method follows the same __module__ + importlib pattern already used by
the check_version property.

* Add changelog entry for _get_package_dir

* Add caching, __path__ fallback, and tests for _get_package_dir

- Cache result in self._package_dir to avoid repeated computation
- Use self.__module__ for consistency with check_version
- Fall back to package.__path__[0] for namespace packages
- Raise RuntimeError with descriptive message when neither
  __file__ nor __path__ is available
- Add 4 unit tests covering: return type, caching, namespace
  package fallback, and error case

Add Claude Code PR review artifacts to .gitignore

* Fix flaky test_compute_derivative_rows_mem_usage

Replace tracemalloc peak threshold check with direct assertion on
_previous_statements contents. The old test was sensitive to Python
version, GC timing, and ddtrace profiler overhead, causing it to exceed
the 10 MB threshold on Python 3.13 in CI (measured ~105 MB).

The new test directly verifies the property that matters: after calling
compute_derivative_rows, the cache only contains metric columns (e.g.
count, time) and not the full row data (e.g. the large query strings).

* Report all cache violations at once in test assertion

* Remove .agint-review from .gitignore, handled in separate PR

* [mongo] Add propagate_agent_tags support

Add the `propagate_agent_tags` configuration option to the MongoDB
integration for parity with PostgreSQL, MySQL, and SQL Server. When
enabled, agent host tags from datadog.yaml are propagated to the check's
metric and service check tags, reducing config duplication for proxy
agents monitoring multiple MongoDB nodes.

* Address PR review: is_affirmative + integration tests

- Use is_affirmative() in _should_propagate_agent_tags to handle string
  values like "false"/"true" from env-templated YAML configs
- Add string coercion test cases ("true"/"false") to unit tests
- Add negative-path assertions (agent tags absent when disabled)
- Add integration tests running against live MongoDB 8.0
