Use MIMI_SPIFFS_BASE to centralize file path definitions, making the
base path configurable instead of hardcoded.

On ESP IDF 5.5 the get_current_time tool returns ESP_ERR_NOT_FOUND because
there is no "Date" header. This is because esp_http_client_get_header
only reads request headers. Response headers are only available via the
HTTP_EVENT_ON_HEADER event callback. They're dispatched and freed as they're
parsed.
Register an event handler that captures the "Date" header during HTTP response
parsing. The date string from this header is available as part of user context
after the HTTP request is finished.
- Remove unused context_build_messages() (superseded by direct cJSON in agent_loop)
- Remove unused llm_chat() and its helper extract_text_* functions (superseded by llm_chat_tools)
- Remove ota_manager.c from build (never called)
- Remove config_screen.c stub from build (no-op module)
- Remove unused PWR_KEY_State, Button_GPIO_Get_Level; drop config_screen dependency from button_driver
- Fix incorrect type cast in tool_get_time.c (char[64] cast to char**)

Bring back two-layer configuration: build-time defaults from mimi_secrets.h
with runtime NVS overrides via serial CLI. NVS values take highest priority
so a pre-flashed board can be reconfigured anywhere with just a USB cable.
Restored CLI commands: wifi_set, set_tg_token, set_api_key, set_model,
set_proxy, clear_proxy, set_search_key. Added new commands: config_show
(displays all config with sensitive fields masked), config_reset (clears
all NVS overrides), and help (lists all commands).

All configuration is now done exclusively through mimi_secrets.h at build time.
Removed NVS read/write logic, CLI config commands (wifi_set, set_tg_token,
set_api_key, set_model, set_proxy, clear_proxy, set_search_key), and setter
functions from all modules. CLI retains debug/maintenance commands only.
Updated all documentation to reflect the change.

Enable the agent to persist memories by adding 4 SPIFFS file tools
(read_file, write_file, edit_file, list_dir) with path validation,
and update the system prompt with memory guidelines pointing to
/spiffs/memory/MEMORY.md and daily notes.

Fetches real time via HTTP Date header (works through proxy),
sets system clock, and returns formatted local time to the agent.
Also adds MIMI_TIMEZONE config and updates default model to claude-opus-4-5.

Replace SSE streaming with non-streaming JSON for Anthropic API.
Add llm_chat_tools() returning structured llm_response_t with text
and tool_use blocks. Implement tool registry with dispatch-by-name
and web_search tool via Brave Search API (direct + proxy support).
