fix(detect): prune .vibe/ from scans (#2537)

Vibe's project-scope install dir (.vibe/) holds graphify's own skill,
agent, and hook artifacts — scanning it wastes semantic extraction on
config files instead of real code. Add .vibe to _SKIP_DIRS so it is
pruned by default, matching how .graphify and graphify-out are handled.
