# File Objective  : CLI to refresh keyword signals and print the ranked momentum table.
# Scope           : Dev script — verify signals.json is written and cache-aside works.
# What it does    : Calls fetch_signals() then prints all keywords sorted by momentum.
# What it does not: Compute coverage or GapScore — that is the gap module's job.
