/**
 * Load the in-process Code Mode NAPI addon.
 *
 * Same model as MCP: Rust `CodeModeSession` runs inside the Node process.
 * No `asgrep` CLI spawn on the hot path.
 *
 * Resolution order:
 * 1. `ASGREP_CODEMODE_NAPI_PATH` (dev override)
 * 2. `@ast-sgrep/<platform>/ast-sgrep-codemode.node` via launcher (release install)
 * 3. Local `extension/native/` / cargo `target/release` (dev builds)
 *
 * Severed-lane policy: the in-process binding requires an exact native
 * generation (an ABI mismatch risks crashes, not errors). Older launchers
 * serve Code Mode over CLI sticky/batch/spawn instead — same tools, slower.
