v0.6.3 Release Notes

Fixed

• Antigravity global sync path: Updated Antigravity 2.0 global skill sync to ~/.gemini/config/skills so synced skills are discovered by current Antigravity versions (#79).
• Windows updater metadata: Added Windows updater signatures and windows-x86_64 / windows-aarch64 platform entries to updater.json, fixing update checks on Windows (#78, PR #82).
