GrokDesk v0.1.9

Fixed

• Optional x.ai/* ACP capability probes that return JSON-RPC -32601 Method not found now fall back quietly instead of appearing as a conversation failure.
• Standard ACP session and prompt failures remain visible.
• Capability calls still receive the original failure for local fallback and diagnostics.

Validation

• ACP unsupported-extension regression passed.
• Release build and deep code-signature verification passed.
• DMG checksum verification passed.
• Sparkle appcast generated for v0.1.9.
