feat(usage): PowerUse-Zeitfenster + Handoff-Schwellwert als Settings

Drei neue app_settings-Spalten (Migration AddPowerUseWindow):
power_use_window_start/end (HH:mm, lokal, nullable) und
power_use_handoff_pct (NOT NULL DEFAULT 95, geclampt 50-99).

Die Fensterlogik liegt als reine Funktion in PowerUseWindow
(Contains/Normalize/IsOpen): beide Grenzen leer oder nur eine gesetzt =
rund um die Uhr, Ende vor Start wrappt ueber Mitternacht, Grenzen
halboffen. Geprueft wird in ComposeHandlerPromptAsync, also pro Phase
zum Zeitpunkt des Prompt-Baus - die Uhr ist per Func<DateTime>
injizierbar. Bedienung im Usage-Monitor neben dem PowerUse-Toggle
(Commit auf Blur/Enter, ein Write fuer alle vier Felder); in
Settings->General unsichtbar, aber load->save durchgereicht.

Nebenbefund, gleicher Pfad: AppSettingsRepository.UpdateAsync kopiert
Feld fuer Feld und hat ModelPresets, PowerUseEnabled und
ListHandlerMaxHandoffs nie geschrieben - jeder Save dieser drei war
still wirkungslos. Mit ergaenzt und per Round-trip-Test gepinnt.

| `NextTaskNumber` | `next_task_number` | 1 | Persistent counter for `TaskEntity.Number` allocation. Incremented atomically in `TaskNumberAllocator.AddWithNumberAsync` on every task insert. **Monotonic only:** the counter itself advances across all tasks (no per-list numbering), and it never resets. A deleted task leaves a gap. |
| `PowerUseEnabled` | `power_use_enabled` | false | PowerUse master switch, toggled on the **usage monitor** (not Settings). ⚠️ Never sufficient alone — a handler run is in PowerUse only when `list_config.power_use_allowed` is also set. |
| `ListHandlerMaxHandoffs` | `list_handler_max_handoffs` | 4 | Cap on a list-handler run's wait↔merge handoff chain (`HandoffRoundTracker`). 4 = two merge rounds. Independent of PowerUse — applies to interactive runs too. Clamped to min 1 in `WorkerHub.UpdateAppSettings` and again in `Register`, because 0 would remove the only bound on a runaway chain. |
| `PowerUseWindowStart` / `PowerUseWindowEnd` | `power_use_window_*` | null | Optional local-time window (`HH:mm`) narrowing when PowerUse applies. Both null (or only one set) = round the clock, i.e. byte-identical to the pre-window behaviour; end before start wraps over midnight. Semantics live in the pure `PowerUseWindow`; checked in `InteractiveLaunchSpecService.ComposeHandlerPromptAsync` **per phase** at prompt-build time, so a chain handing off past the end time drops the addendum from there on. Unparseable input is stored as null, not rejected. |
| `PowerUseHandoffPct` | `power_use_handoff_pct` | 95 | 5h-usage percentage at which a PowerUse handler session should hand off. Clamped 50..99. Stored + shown on the usage monitor; the consumer is the handoff prompt. |
All four usage percentages are clamped 0..100 by `AppSettingsRepository.UpdateAsync`.
Gate/throttle semantics → [usage-monitoring](../../docs/explore-notes/usage-monitoring.md).
⚠️ **`AppSettingsRepository.UpdateAsync` copies the incoming entity field by field** onto the
singleton row — a property missing from that block never persists, however correctly the caller
filled the entity, and nothing fails. `ModelPresets`, `PowerUseEnabled` and
`ListHandlerMaxHandoffs` were all silently unwritable that way until 2026-09-02. Add a new column
to that block, not just to the entity + the hub.
### Model / effort registries
- **ModelPresets / ModelPreset** — per-model run defaults (`Model`, `Effort`, `MaxTurns`), one row per `ModelRegistry.Aliases` entry, supplying the **global** effort and max-turns defaults. Ship defaults: haiku medium/20, sonnet high/30, opus high/40, fable high/25. `Parse`/`Serialize` normalize (unknown models dropped, missing aliases filled from `Defaults`, effort validated, turns clamped 1–200) and **never throw** — a malformed settings row must not stop a run. `For(presets, model, fallbackMaxTurns)` always returns a usable row; resolution order and the fallback trap → [worker-task-pipeline](../../docs/explore-notes/worker-task-pipeline.md).
