Rename gemini-resume → antigravity-resume and save_gemini_session → save_antigravity_session; update all session files from .gemini_session to .antigravity_session and LAST_GEMINI_SESSION → LAST_ANTIGRAVITY_SESSION. Replace gemini/gemini-cli binary calls with agy throughout superpowers, code-resume, and the resume function. Add antigravity-ide wrapper for the renamed IDE binary; update abbr v → antigravity-ide (VSCode-equivalent) and update README/requirements to reflect the new tool names.
