+Lean-owned MCP surface for ENE context memory operations.
+
+This file is *surface only* (names + schemas + descriptions). Runtime shims must not
+invent alternate tools; they should load and expose this manifest.
+
+Execution plumbing is provided by non-Lean runtimes (Rust) and must be keyed off
+these tool names.
