feat: el-ide — native IDE for engram-lang, LSP, type graph, plugin ecosystem

Axum HTTP server (port 7771) serving a single-page IDE with CodeMirror 6 syntax highlighting for engram-lang, a force-directed type graph visualizer, LSP (completions, hover, diagnostics), SSE-streamed build/run output, a plugin host with five first-party plugins, and a reasoning panel that proxies to engram-server. 28 tests across three crates, zero warnings.
