v2.1.1: bump opencode 1.17.5->1.17.6

Patch release. Upstream 1.17.6 is a single MCP-compatibility bugfix (no breaking/runtime/AVX changes). Also lands the unreleased mempalace-toolkit SHA-resolution CI fix and two doc corrections; the toolkit change advances the base hash so this carries a base rebuild + base-latest re-promote.
