fix: escape percent sign in --no-session-cache help string

borhend · borhend · commit cb2f06e7e762 · 2026-06-15T11:05:32.000+01:00
The help string contained '90% discount' which argparse interpreted as a %%d format specifier (expecting a number, receiving a dict). Python 3.14 added strict _check_help() validation, causing a crash on startup even for --version. Also corrected the savings figure to the honest ~73%%. Closes #5
