/**
 * cli/driver.mjs — bundled headless CLI driver.
 *
 * Targets non-GUI CI verify-proof runs. Asserts on command stdout / stderr
 * and on captured log streams. The transport is `{ builtin: true }` — the
 * driver itself shells out via packages/framework/src/cli/verify-proof/exec.mjs
 * (execFile, no shell) for the rare cases it needs to spawn a tool.
 *
 * Capabilities (5, the AC8 minimum):
 *   - execute_js — run a Node snippet via execFile('node', ['-e', script])
 *   - capture_logs — append stdout/stderr to an evidence file
 *   - assert_output — match an expected pattern against stdout/stderr
 *   - assert_text — match against a captured text artifact
 *   - dump_state — write a JSON describing the runner's CWD + env keys
 *
 * Per ID-03 — `transport: { builtin: true }` means the driver IS the
 * transport; it never shells out to free-form strings. Any `execute_js`
 * invocation routes through exec.mjs which uses execFile (no shell).
