* Block L1 — Sleep Mode tests.
*
* Covers:
* - `renderSleepModeDigest` HTML + plaintext output, including XSS resistance
* - `computeHoursSaved` heuristic
* - autopilot `sleep-mode-digest` task: cooldown, hour-match, enabled filter,
* per-tick cap, per-user failure isolation
* - `/sleep-mode` public marketing page returns 200
* - `composeSleepModeReport` zero report for a user with no repos
*
* DI test pattern follows K3's `autopilot-ai-tasks.test.ts` — every DB call is
* dependency-injected so tests run without a real DB.
