/**
 * `kern migrate native-handlers` — rewrite raw `<<<…>>>` handler bodies to
 * inferred-KERN body-statement form.
 *
 * Input:  raw JS body in `<<<…>>>` that passes the slice 5a `classifyHandlerBody`
 *         eligibility check (no arrow functions, unsupported loops, unsafe mutation,
 *         regex literals, console/process/req/res access, …).
 *
 * Output: `handler` with structured body-statement children
 *         (`let`/`return`/`if`/`else`/`try`/`catch`/`throw`). The parser
 *         infers `lang="kern"` for this shape, so the migration no longer
 *         emits explicit opt-in boilerplate.
 *
 * Anything outside the supported AST shape causes the whole handler to be
 * skipped — never half-migrated. Verify mode (`--verify`) is the safety net:
 * it pre-compiles, applies the migration, recompiles, and rolls back on any
 * codegen drift.
