Enable ESP32-S3 to reach api.telegram.org and api.anthropic.com through an HTTP CONNECT proxy (e.g. Clash Verge), required in regions where these services are blocked. - New proxy module (http_proxy.c/h): CONNECT tunnel + TLS via esp_tls with pre-connected socket injection (esp_tls_set_conn_sockfd) - Telegram and LLM modules split into direct/proxy paths - CLI commands: set_proxy <host> <port>, clear_proxy - Proxy config persisted in NVS - Fix TLS buffer: MBEDTLS_SSL_IN_CONTENT_LEN 4096 → 16384 - Increase task stacks for TLS overhead (poll 12KB, agent 12KB, outbound 8KB) - Default model changed to claude-opus-4-6 - Capture raw error body for non-200 API responses Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
