"""CLI wrapper around inject_section() from _common.

Injects content between TOOLKIT markers into any file.
Existing content outside the markers is preserved -- never overwritten.
Re-running updates only the marked section (idempotent).

Usage:
  inject_section_cli.py <content-file> <target-file> [section-name]

Arguments:
  content-file  Path to file with content to inject
  target-file   Path to target file (created if missing)
  section-name  Marker label (default: ai-toolkit)
