- cargo-chefイメージをrust 1.87から1.97.1に更新 (rust-toolchain.tomlと同期)。
  sentry 0.48.5やtime 0.3.47がrustc 1.88以上を要求するため、2026-04-10以降
  Build and releaseワークフローが失敗し続けていた
- 実行ステージのubuntu:24.04 (glibc 2.39) でバイナリが動くよう、
  デフォルトのtrixie (glibc 2.41) ではなくbookworm variantを明示指定
- mariadb_repo_setupのsha256をMariaDB公式の現行版 (2026-06-30) に更新

旧 Sentry (sentry.onp.admin.seichi.click) は配信面が撤去済みで
(GiganticMinecraft/seichi_infra#5613)、ハードコードされた DSN への
送信は既に到達不能だった。seichi-portal-backend と同じ観測スタックへ移行する:

- OTel トレーシング: OTLP http/protobuf、OTEL_* 環境変数で設定。
  OTEL_EXPORTER_OTLP_ENDPOINT 未設定 / OTEL_SDK_DISABLED=true なら無効
- HTTP サーバースパン: axum-tracing-opentelemetry (Sentry の tower layer を置換)
- stdout ログ: 本番は 1 行 JSON + OTel trace_id 注入 (json-subscriber)。
  panic hook が panic=true / level=ERROR を付ける (seichi_infra の
  LogQL ルールとの契約。portal-backend の panic_hook.rs と同一)
- handler 内 panic は CatchPanicLayer で 500 を返しつつ hook がログに残す
- 継続プロファイリング: Pyroscope への push (pyroscope crate、
  PYROSCOPE_SERVER_ADDRESS 未設定なら無効)

telemetry / logging / panic_hook は seichi-portal-backend の実装 (レビュー済み) の移植。
