#      see CONTEXT7_API_KEY / EXA_API_KEY / Z_AI_API_KEY / TELEGRAM_* / etc.
#   2. Auto-prepends --yolo (-y) to make Gemini autonomous by default.
#   3. Forwards all args to the REAL gemini binary further down PATH.
#
# Opt out of YOLO for a single run:
#   gemini --no-yolo ...
#   GEMINI_NO_YOLO=1 gemini ...
#
# Bypass this shim entirely:
#   command -v gemini -a       # see all gemini binaries
#   /usr/local/bin/gemini ...  # call the real one directly
