hanzoai 2.2.1: ship hanzoai.protocols

protocols.py landed 2026-03-31 (200cef23) but 2.2.0 was published before
it, so the module never reached PyPI. hanzo-mcp imports
hanzoai.protocols at startup; resolving against the published 2.2.0
crashed every stdio launch with ModuleNotFoundError before the
initialize response — surfacing as 'Failed to connect' in Claude
Desktop/Code.

 # Changelog
 
+## 2.2.1 (2026-06-10)
+
+### Bug Fixes
+
+* ship `hanzoai.protocols` (in-tree since 2026-03-31 but never released) — `hanzo-mcp` imports it at startup, so installs resolving `hanzoai==2.2.0` crashed with `ModuleNotFoundError` before answering MCP `initialize`
+
+### Chores
+
+* remove dead release-please machinery (config, manifest, release-doctor workflow); releases are tag-driven via `publish-pypi.yml`
+
 ## 2.0.2 (2025-04-04)
