Three independent upstream CI fixes that currently fail on every open PR:
verify_import_hoist.py: TARGET-CHANGED only flags a genuine swap (a BEFORE
target no longer reachable in AFTER). A pure superset growth such as adding
import urllib.error next to import urllib.request binds the same top-level
package and loses nothing, so it is no longer a blocker (transformers_version.py).
test_vision_cache.py: run each test from a fresh empty cwd. is_vision_model
calls is_local_path first, and a relative model id that happens to exist on
disk short-circuits before the mocked detection runs; the CI cwd and HF cache
can contain dirs colliding with the synthetic ids, causing 'called 0 times'.
Production code is correct; only the test needed cwd isolation.
consolidated-tests-ci.yml: the llama.cpp smoke probes the first of
llama-cli / llama-mtmd-cli / llama-server that exists instead of hard-requiring
llama-cli, which upstream no longer always builds. llama-cli stays first so it
is preferred when present. Adds Windows .exe + build/bin/Release handling.
