# Claude CLI wrapper that patches the footer flex layout so the statusline
# renders on its own row, while hints and notifications share a second row.
# See: https://github.com/anthropics/claude-code/issues/27305
#
# The patch is applied idempotently to cli.js on each launch, so Claude
# Code updates are automatically re-patched on next run.
