refactor(sf): rename sift cache env to SIFT_SEARCH_CACHE

Browse source 
Switches the per-project sift warmup runtime dir field from cacheHome
(generic XDG_CACHE_HOME) to searchCache (specific SIFT_SEARCH_CACHE).
Narrower env var only redirects sift's search index, leaving sift's
other XDG_CACHE_HOME consumers (model downloads etc.) on the global
~/.cache/sift path so models are shared across projects.
