wavekat-cli 0.0.16

//! `wk files …` — list project files, manage the test-set reservation
//! flag (docs/08-test-set-reservation.md).
//!
//! Reservation maps onto two endpoints:
//!   POST   /api/files/{id}/test-reservation     (idempotent)
//!   DELETE /api/files/{id}/test-reservation     (idempotent)
//! Both are owner/root-gated server-side; the CLI just reflects whatever
//! the API returns.
