Translate README, comments, and notification text to English

Covers the README, all code comments in server.js and .env.example,
diagnostic log messages, and the push/pull_request summaries sent to
the Claude Code routine, so the whole codebase and its output are
consistently in English.

 # Gitea-Claude-Webhook-Proxy
 
-Proxy en Node.js/Express que recibe webhooks de Gitea y los reenvía a la API
-de Claude Code Routines, añadiendo los headers que Gitea no permite
-configurar (`Authorization: Bearer <token>`, `anthropic-beta`,
+Node.js/Express proxy that receives Gitea webhooks and forwards them to the
+Claude Code Routines API, adding the headers Gitea can't be configured to
+send itself (`Authorization: Bearer <token>`, `anthropic-beta`,
 `anthropic-version`).
 
-## Cómo funciona
+## How it works
 
-1. Gitea hace `POST` a `/gitea-webhook` con:
-   - Header `Authorization: <secreto-A>` (configurado a mano en Gitea).
-   - Header `X-Gitea-Signature`: HMAC-SHA256 del body crudo con el `Secret`
-     del webhook.
-2. El proxy valida ambos (comparación constant-time) y responde 401 si no
-   coinciden.
-3. Deduplica por `X-Gitea-Delivery` (TTL configurable) para no reenviar
-   reintentos de Gitea.
-4. Construye un `text` legible a partir del payload (`push`, `pull_request`;
-   cualquier otro evento cae en un mensaje genérico) y responde `200` a
-   Gitea de inmediato.
-5. En segundo plano, hace `POST` a
+1. Gitea sends a `POST` to `/gitea-webhook` with:
+   - Header `Authorization: <secret-A>` (configured by hand in Gitea).
+   - Header `X-Gitea-Signature`: HMAC-SHA256 of the raw body using the
+     webhook's `Secret`.
+2. The proxy validates both (constant-time comparison) and returns 401 if
+   either one doesn't match.
+3. It deduplicates by `X-Gitea-Delivery` (configurable TTL) to avoid
+   reprocessing Gitea retries.
+4. It builds a readable `text` from the payload (`push`, `pull_request`;
+   any other event falls back to a generic message) and responds `200` to
+   Gitea immediately.
+5. In the background, it makes a `POST` to
    `https://api.anthropic.com/v1/claude_code/routines/{ROUTINE_ID}/fire`
-   con el `text` y loguea el resultado (éxito, 401/429/5xx, o fallo de red)
-   sin tumbar el proceso.
+   with that `text` and logs the outcome (success, 401/429/5xx, or a
+   network failure) without crashing the process.
