Replace all ad-hoc inline comments between license headers and function
declarations with consistent SYNOPSIS / DESCRIPTION / ARGUMENTS / RETURNS /
EXAMPLE blocks across all 99 project-owned functions/ files. No executable
logic, variable names, or exit codes were modified.
Completes Task #6 from AGENTS.md (Retroactive Function Documentation
Standardization).
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.
