feat(rituals): Phase 5 — morning triage, evening wind-down, autostart

Three opt-in rituals, all default OFF. Research-anchored (Barkley's
point-of-performance, Sweller cognitive-load theory, Newport shutdown
ritual, Gollwitzer implementation intentions, Thaler/Sunstein nudge
with informed consent for the ADHD audience).

Morning triage: modal gated on ritualsMorning toggle, configurable
trigger time (default 08:00 to respect ADHD sleep inertia rather than
the spec's 06:00), "pick up to three for today" with a gentle swap
message on the fourth attempt. Skip sets last-shown-today so it never
re-prompts the same calendar day. last-shown persists via kon_storage.

Evening wind-down: dedicated page, user-triggered only (tray menu +
Settings button). Mechanical closure + physical reset + intentional
cue — the whole Newport template. Open loops are read-only reflection;
Tasks page owns transactions. Copy is additive throughout: "you
finished X today", never "you didn't finish Y".

Autostart: tauri-plugin-autostart registered (LaunchAgent on macOS,
.desktop on Linux, registry Run on Windows). No bespoke Rust commands
— frontend calls the plugin's invoke-handlers directly. Toggle in
Settings is one-way (click → OS call → state update) to avoid the UI
lying during the round-trip. First-run presents a forced-choice prompt
for all three options, with "skip all" escape hatches per step.

Copy audit against RSD literature: no "overdue", "failed", or
day-to-day comparison framing anywhere in ritual surfaces.

Post-v0.1 ideas captured in the roadmap: calendar integration
(read-only ICS as interim, cloud sync parked) and right-click-to-task
(in-app simple, system-wide a separate phase).
