Add Ely-Eye MCP server

Local read-only Model Context Protocol server (Go) exposing the .ely_eye memory
store to coding agents such as Codex and Claude Code: nine tools over status,
cartridges, Evidence Atoms, compiled evidence packs, proof suites, and HashHop
proofs. One-line cross-platform install (no Docker), with a prebuilt-binary
release workflow.

+## MCP server for coding agents
+
+`ely-eye-mcp/` is a local Model Context Protocol server that exposes the
+`.ely_eye` memory store to coding agents such as Codex and Claude Code. One
+command builds a native Go binary (or downloads a prebuilt one), installs it
+under `.ely_eye/bin/`, and registers it with both clients. No Docker.
+
+Windows:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\ely-eye-mcp\install.ps1 -Client both
+```
+
+Linux and macOS:
+
+```bash
+bash ./ely-eye-mcp/install.sh --client both
+```
+
+The agent then has nine read-only tools over the live memory — status,
+cartridge listing and detail, Evidence Atom search and fetch, evidence-pack
+compilation, proof suites, and HashHop proofs. The server opens the database
+read-only and never writes to it. The same installer works against any
+`.ely_eye` store, not only this repository. See `ely-eye-mcp/README.md` for the
+full tool list and the release pipeline.
