Adds utils/generation_params.py, a line-for-line port of
extractGenerationParams in web/js/comfy-metadata.js, the parser behind
the gallery, admin and metadata pages. The scan and live monitor can use
it so every surface reads prompts the same way. The JavaScript parser is
unchanged.
The port reproduces the JavaScript value semantics the result depends on
(property order, truthiness, String(), trim(), strict equality, Map keys,
JSON.parse number rounding, and the inputs on which it throws), and runs
its recursive tracing on an explicit stack so crafted graphs cannot
exhaust the Python stack.
Tests:
- behaviour tests for each tracing rule, with JavaScript results as
expected values, including the visit-limit boundary;
- golden vectors of the JavaScript parser's results for every named case
and every PNG fixture, so the comparison runs without Node;
- a live comparison against the JavaScript parser when Node is present;
- a randomized differential test over 9,000 generated graphs and
workflows, coherent and corrupted, including inputs where the
JavaScript throws.
Five deliberate porting mistakes (trim, truthiness, prepend handling,
visit limit, pair slot) each fail the tests. On a 38,602-file output
folder, all 18,491 files with a workflow give identical results.
