paper stdio mcp

[itsdouges]

Updates the existing plugins to point to paper stdio mcp. Removes the codex plugin as it doesn't support dynamic path expansion with PATH.

Note

Low Risk
Changes are packaging, docs, and MCP wiring only; users on the old HTTP MCP or Codex installs need to migrate, but no application runtime or security-critical logic is modified in this repo.

Overview
MCP connection moves from an HTTP server at 127.0.0.1:29979 to a stdio process: mcp.json uses ${HOME}/.paper/bin/paper with args: ["mcp"], and mcp-installed.json adds a variant that invokes paper on PATH the same way.

Codex is removed end-to-end: .agents/plugins/marketplace.json, plugins/paper-desktop/.codex-plugin/plugin.json, Codex install docs in the root README, and scripts/validate-codex.mjs (dropped from the package.json build script).

paper-desktop 0.2.0 updates Claude and Cursor manifests. The Claude manifest no longer references skills; the code-to-design / design-to-code skill files and the ensure-paper-started rule are deleted. Plugin README prerequisites are shortened to install Paper Desktop and open it once.
