Add comprehensive test suites for answer key validation, API functionality, and code linting

- Introduced `test_answer_key.py` to validate the correctness of answer keys against expected responses, ensuring both false and true answers are graded appropriately.
- Created `test_answer_values.py` to verify the accuracy of answer keys by recomputing values and comparing them against the provided `answers.json`.
- Implemented `test_api.py` to test the HTTP API for suite management, ensuring read-only enforcement and proper handling of custom suites.
- Added `test_code_lint.py` to perform static code analysis, ensuring that all linting rules are enforced without false positives on correct answers.
- Developed `test_collision.py` to guard against prompt mismatches due to filename collisions across suites.
- Created `test_gguf.py` to validate GGUF header parsing and model classification, including handling of malformed input.
- Introduced `test_linter.py` to ensure report rendering preserves content integrity and correctly fences code.
- Added `test_reporting.py` to verify report naming conventions and the accuracy of per-suite score breakdowns.

# Python tests
```bash
python tests_py/run_all.py # everything
python tests_py/run_all.py gguf key # only files matching those words
python tests_py/test_linter.py # one file directly
```
Exits non-zero if anything fails, so it works as a CI entry point.
No third-party dependencies. `test_api.py` needs a running server
(`python app.py`) and the `requests` package the LM Studio provider already
uses; it prints `SKIP` and passes when the server is down, so the rest stay
useful offline.
| File | Covers |
| --- | --- |
| `test_answer_values.py` | The answer keys themselves, recomputed from scratch |
| `test_answer_key.py` | The correctness grader, both directions |
| `test_api.py` | Suites API, read-only guards, run selection |
| `test_code_lint.py` | Static code rules, and the false positives they must not repeat |
| `test_collision.py` | Qualified question IDs |
| `test_gguf.py` | GGUF header parsing and model classification |
| `test_linter.py` | Report rendering |
| `test_reporting.py` | Report naming and the per-suite breakdown |
The UI tests live separately, under `web/src/**/*.test.tsx` — run them with
`cd web && npm test`.
## Why these are scripts rather than `unittest` cases
They exercise a diagnostic tool, so the output is read as much as the exit
code. `test_code_lint.py` is a table of which rules fire on which input, and
that is worth more when debugging a false positive than a row of dots.
`run_all.py` aggregates exit codes for the times you only want a verdict.
Each file runs in its own process. Several load plugins directly, which would
otherwise collide in `sys.modules`.
## `test_answer_values.py` is the one to keep honest
The other files test code. This one tests **data** — it recomputes every
numeric answer key with exact arithmetic and brute-force search, then asserts
the shipped `answers.json` agrees.
That matters because a wrong key fails correct work with total confidence,
which is the exact failure the answer-key grader exists to remove. It earned
its place immediately: the Winograd referent had been recorded backwards, and
shipping it would have marked every correct answer wrong.
If you add or edit a key, add the computation here too. A key nobody can
re-derive is a liability.

"""Shared scaffolding for the Python tests. No third-party dependencies.
Lives in ``tests_py/`` rather than ``tests/`` because that name is taken: it
holds user-created custom suites, and mixing test code into it would be
confusing even though suite discovery only looks at directories.
Tests are plain scripts rather than ``unittest`` cases. They exercise a
diagnostic tool, so their output is read as much as their exit code — the
code-lint file, for instance, is a table of which rules fire on which input,
and that is worth more than a dot per assertion. ``run_all.py`` aggregates
exit codes for CI-style use.
