### Description

When Serena AI is used in the repository, it creates a directory
within the project containing project memories (where it
stores the results of indexing the project).

Adding this to the `.gitignore` so as to avoid accidentally committing
it in the future.

#### Issues
No issue associated with this change

Update our test matrix with new releases of integrated frameworks and
libraries.

## How it works
- Scan PyPI for all supported releases of all frameworks we have a
dedicated test suite for.
- Pick a representative sample of releases to run our test suite
against. We always test the latest and oldest supported version.
- Update
[tox.ini](https://github.com/getsentry/sentry-python/blob/master/tox.ini)
with the new releases.

## Action required
- If CI passes on this PR, it's safe to approve and merge. It means our
integrations can handle new versions of frameworks that got pulled in.
- If CI doesn't pass on this PR, this points to an incompatibility of
either our integration or our test setup with a new version of a
framework.
- Check what the failures look like and either fix them, or update the
[test
config](https://github.com/getsentry/sentry-python/blob/master/scripts/populate_tox/config.py)
and rerun
[scripts/generate-test-files.sh](https://github.com/getsentry/sentry-python/blob/master/scripts/generate-test-files.sh).
See
[scripts/populate_tox/README.md](https://github.com/getsentry/sentry-python/blob/master/scripts/populate_tox/README.md)
for what configuration options are available.

Add initial `agents.toml` and `agents.lock` files to support `warden`
setup across the team. While not strictly required, this configuration
allows `warden` to discover and load skills from the `.agents` folder,
making initial setup easier for developers.

…etsentry#5485)

### Description
The skills added in these changes include the ones that are specified in
the `warden.toml` (from the `sentry/skills`
[repo](https://github.com/getsentry/skills)).

The reason for the `pyproject.toml` change is because the script inside
the `skill-scanner` skill uses Python 3.8+ syntax (in this case the
named assignment, a.k.a. the "walrus", operator). This project, due to
supporting Python 3.7+, flags such syntax using ruff.

Given this skill script is for development/CI pipeline purposes and will
not be shipped in SDK code that is operating within user applications, I
thought that ignoring this in ruff is okay in this context.

#### Tradeoffs made
I considered using the `.claude` rather than the `.agents` folder as the
source of the skills to remove the dependency on the
[`dotagents`](https://github.com/getsentry/dotagents/) tool for the
benefit of other users if they didn't wish to install another tool.

However, having it in `.agents` allows everyone to benefit from the
`agents.lock` file that ensures consistent skill installations in the CI
pipeline and locally.

### Description
Adds warden code reviews to our Github workflows.

Remove all `gen_ai.invoke_agent` spans from the `google-genai` integration. 

The agent spans in `google-genai` only wrapped simple model requests, duplicating attributes already captured by `gen_ai.chat` spans. An agent span must capture multiple model calls, or some auxiliary work that goes beyond transforming the model input and output.

Avoid consuming single-use iterators passed to the Embeddings API.

All iterables that are not dictionaries or strings are transformed to lists in the internals of `openai` before they are passed to an API call.
