kg-memory 0.12.0: one command, kg mcp for every harness, on PyPI

Breaking: the plugins now need the kg command. Install once with uv tool install kg-memory && kg setup; a session without it says how. Memory data is unchanged.

Added

• kg, one command for the memory, published on PyPI as kg-memory. kg setup checks every piece and fixes what you accept, backing up each file first: the command on PATH, a systemd user service on Linux, the server, and for Claude Code, Codex, Antigravity and Claude Desktop the plugin, permissions and settings. kg doctor checks, kg update upgrades kg, the server and every plugin together, kg uninstall reverses setup and keeps your memory. Also kg start/stop/restart/status/logs/commit and kg gauge (the Claude status-line quota tap).
• kg mcp: every harness connects over stdio. It starts the server when it is down and waits out a restart, then retries, so the tools stay connected instead of needing /mcp → Reconnect. Only a refused connection is retried, so a write never lands twice. Claude Code, Codex, Antigravity and Claude Desktop all use it; Desktop no longer needs Node or the mcp-remote bridge.
• kg editor starts the visual editor (and the server it reads) and opens it.
• Releases publish to PyPI from the version tag through trusted publishing.

Changed

• The SessionStart hooks start the server through kg and wait for it, so a cold start still gets its preload.
• kg start is serialised: concurrent starts from a harness and its hook share one server instead of leaving a false start error.
• The server refuses to run twice on the same storage directory.
• The repository is now mironmax/kg-memory; the old URL redirects and installed marketplaces keep working.

Removed

• The plugin's own launchers: server/manage_server.sh and its per-plugin Python environment, install_command.sh (kg-memory/kg-visual links), setup_desktop.py and desktop_bridge.sh, visual-editor/manage_visual.sh, and the memory-mcp.service unit. kg setup retires the old links and moves an existing Desktop entry to kg mcp; kg-memory stays as a shim that runs kg.
