Merge branch 'master' into fix/validate-node-executable

Addresses review feedback: the V1 executability check fell back to
constructing the node (class_def()) when the FUNCTION method wasn't found on
the class. That runs __init__ during validation, so a constructor's side
effects or failure could be misreported as invalid_node_definition for an
otherwise valid node.

Inspect only the class. No core/extra node defines its FUNCTION method on the
instance, so this loses no real coverage while removing the side-effect risk.

Replace the instance-fallback test with one asserting a node with a raising
__init__ but a valid class-level method still passes validation (i.e. it is
never instantiated).

-"""CI unit guard for FIX #5 of GHSA-779p-m5rp-r4h4 — the /view forced-download set.
-
-Vuln #5 was stored XSS via SVG upload: the /view endpoint's Content-Type
-blocklist covered text/html, text/javascript, etc. but was missing
-image/svg+xml, so an uploaded SVG carrying an inline <script> was served as
-image/svg+xml and executed in the page origin when rendered.
-
-The /view forced-download decision lives in the view_image closure registered by
-server.PromptServer.add_routes (server.py ~line 596), which calls
-`folder_paths.is_dangerous_content_type(content_type)` — a normalising check that
-strips charset/boundary parameters and casing and folds in the whole */xml and
-*+xml dialect family — rather than a bypassable raw
-`content_type in folder_paths.DANGEROUS_CONTENT_TYPES` membership test. On a match
-it rewrites the response to application/octet-stream with a
-Content-Disposition: attachment header. server.py cannot be imported in a unit
-test (importing it spins up the full PromptServer/aiohttp app and its global side
-effects), so these tests pin the underlying dangerous-content data
-(folder_paths.DANGEROUS_CONTENT_TYPES) and the normalising is_dangerous_content_type()
-helper that the closure actually calls.
-
-The end-to-end /view assertion (upload an SVG, GET /view, confirm the response
-is not served as image/svg+xml) lives in the live POC at
-.security/pocs/test_security_ghsa_779p.py::TestViewSvgContentType, which
-requires a running server. This file is the fast, server-free CI guard on the
-set contents so the blocklist can't silently regress.
