CLI task stack is 4KB; the 4096-byte stack buffer in cmd_memory_read
was overflowing and corrupting the heap. Use malloc instead.

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

Agent loop runs on Core 1: pops inbound messages, builds system

session, pushes response to outbound queue. PSRAM-allocated buffers.
