v0.8.6

v0.8.6 — Phase 11I: Channel-Level Notification Language

Added

• Per-channel notification language for Telegram: notification_channels.config gains optional language (en / zh-CN), default en — no schema/migration change, existing channels unchanged
• buildTelegramMessage(event, hostname, language) localizes template labels (app title / event / domain / status / time / event ID) and event labels; machine state values stay canonical (ok / down / server_error / client_error, HTTP status codes) to avoid ambiguity
• Channel edit UI: Notification Language dropdown (English / 简体中文); saveTelegramChannelAction validates (invalid_language) and persists with config
• New src/lib/notifications/i18n.ts dictionary + integrity tests (identical key sets across languages)
• Language is independent from the UI locale (cookie-based)

Scope

• Telegram only (webhook / email channels adopt the dictionary later)

Quality

• 800 tests (54 files) — 15 new (parse/ignore language, zh-CN rendering incl. test-notification label, sender body language, action persistence/validation, toChannelView display); tsc 0, lint 0, prettier PASS, build PASS (BUILD_ID CVfpMJqXYG7srT4aZ4GAt)
