kingwl 0a486f09c9 chore: adopt node-addon-landlock-run source as native/ subtree
Bring the node-addon-landlock-run tree (tag v0.0.1, commit 614f7fd) into
native/landlock-run as its source of record: launcher development happens
here, next to the harness consumers, and the standalone repository becomes
the release mirror the tree is exported to for packing and publishing
(procedure in native/README.md). The subtree keeps its own pnpm workspace
and lockfile and is NOT added to the harness workspace: harness installs,
gates, and CI never touch it. The mirror's .github/ stays out of the
subtree; a separate manually-dispatched workflow
(.github/workflows/landlock-run.yml) runs the subtree's CI legs — the
per-architecture native builds, real-kernel launcher proofs, and pack
rehearsal — adapted with working-directory/cache paths.

eslint ignores the subtree like vendor/; AGENTS.md gains the native/
layout line (+5 words on its budget ceiling).

# node-addon-landlock-run
Landlock self-restrict-then-exec launcher for confining subprocesses on Linux: this entry package resolves the per-platform prebuilt binary, runs its functional enforcement probe, and builds its grant argv — consumers never spell launcher flags or parse launcher output themselves.
```js
import { grantArgs, launcherPath, probe } from 'node-addon-landlock-run';
const launcher = launcherPath();
if (probe(launcher) !== 'unusable') {
const argv = [launcher, ...grantArgs({ readOnly: ['/'], readWrite: ['/tmp/work'] }), '--', 'bash', '-c', command];
}
```
The launcher installs a Landlock ruleset on itself and `exec`s the wrapped command; the ruleset is inherited across `execve`, so the whole process tree runs confined. Everything not granted is denied, and launcher failures exit `125` without running the command — fail-closed, never fail-open. The binary contract is pinned in the repo's `docs/cli-contract.md`; the C source rides this tarball (`src/main.c`) for audit.
Platform packages (`os`/`cpu`-selected optional dependencies, no JavaScript inside): `node-addon-landlock-run-linux-x64`, `node-addon-landlock-run-linux-arm64`. On hosts without one, `launcherPath()` returns a deterministic nonexistent path and `probe()` reports `'unusable'` — there is deliberately no install-time compile fallback.
