Mirror the JavaScript layout from PR #21953:
- Move SystemPromptInjection.ql / UserPromptInjection.ql to src/Security/CWE-1427
- Move customizations, query and framework libs to python/ql/lib
- Move the AIPrompt concept to the production Concepts.qll
- Drop the experimental tag; py/system-prompt-injection (high precision) now
joins the code-scanning, security-extended and security-and-quality suites,
while py/user-prompt-injection (low precision) stays out of the default suites
- Move query tests to python/ql/test/query-tests/Security

We now find an alert on this line as we hope to
It is not an alert for _full_ SSRF, though, since that configuration cannot handle multiple substitutions.
- remove `tupleStoreStep` and `dictStoreStep` from `containerStep`
These are imprecise compared to the content being precise.
- add implicit reads to recover taint at sinks
- add implicit read steps for decoders
to supplement the `AdditionalTaintStep`
that now only covers when the full container is tainted.
Looking at the results of the the previous DCA run, there was a bunch of
false positives where `bind` was being used with a `AF_UNIX` socket (a
filesystem path encoded as a string), not a `(host, port)` tuple. These
results should be excluded from the query, as they are not vulnerable.
Ideally, we would just add `.TupleElement[0]` to the MaD sink, except we
don't actually support this in Python MaD...
So, instead I opted for a more low-tech solution: check that the
argument in question flows from a tuple in the local scope.
This eliminates a bunch of false positives on `python/cpython` leaving
behind four true positive results.
This takes care of most of the false negatives from the preceding
commit.
Additionally, we add models for some known wrappers of `socket.socket`
from the `gevent` and `eventlet` packages.
Adds test cases from github/codeql#21582 demonstrating false negatives:
- Address stored in class attribute (`self.bind_addr`)
- `os.environ.get` with insecure default value
- `gevent.socket` (alternative socket module)
