v0.1.15

Fixed

• antigravity agents now get the same find-skills + 5dive-cli default skill inheritance every other type gets. Previously preseed only ran for claude, and the channel-installer seed steps (which cover codex/grok) don't route antigravity at all, so antigravity agents booted with an empty skills dir.
• SKILLS_INSTALL_DIR[antigravity] corrected from .gemini/antigravity-cli/skills (a guess based on agy's state dir layout) to .agents/skills (verified by grepping the agy binary for {workspace}/.agents/skills/{skill_name}/SKILL.md). The upstream npx skills add --agent antigravity fallback path already matched this — header comment was the only thing out of sync.

New preseed_antigravity_agent in agent_setup.sh, dispatched alongside preseed_claude_agent in cmd_create.

Pair with 5dive-api update.sh backfill landing right after to heal existing antigravity agents at the 03:00 cron.
