Drop the save-session/resume system entirely: - functions/save_claude_session.fish, save_antigravity_session.fish (session-start hook scripts) - functions/claude-resume.fish, antigravity-resume.fish, code-resume.fish (consumers of the .claude_session/.antigravity_session files) Also updates docs/fish-config.md (removes the three function sections, drops the session-helper mention from the python3 dependency note) and docs/fish-config.index (removes the orphaned keyword entries). Generated html/wiki/man are rebuilt by build-docs.yml on merge. External hook registrations were removed from ~/.claude/settings.json and ~/.gemini/settings.json (the latter pointed at an already-deleted save_gemini_session.fish); those files live outside this repo.
