* feat: add screenshot and image_info vision tools
Add two new tools for visual capabilities:
- `screenshot`: captures screen using platform-native commands
(screencapture on macOS, gnome-screenshot/scrot/import on Linux),
returns file path + base64-encoded PNG data
- `image_info`: reads image metadata (format, dimensions, size) from
header bytes without external deps, optionally returns base64 data
for future multimodal provider support
Both tools are registered in the tool registry and agent system prompt.
Includes 24 inline tests covering format detection, dimension extraction,
schema validation, and execution edge cases.

* fix: resolve unused variable warning after rebase
Prefix unused `resolved_key` with underscore to suppress compiler
warning introduced by upstream changes. Update Cargo.lock.

* fix: address review comments on vision tools
Security fixes:
- Fix JPEG parser infinite loop on malformed zero-length segments
- Add workspace path restriction to ImageInfoTool (prevents arbitrary
file exfiltration via include_base64)
- Quote paths in Linux screenshot shell commands to prevent injection
- Add autonomy-level check in ScreenshotTool::execute
Robustness:
- Add file size guard in read_and_encode before loading into memory
- Wire resolve_api_key through all provider match arms (was dead code)
- Gate screenshot_command_exists test on macOS/Linux only
- Infer MIME type from file extension instead of hardcoding image/png
Tests:
- Add JPEG dimension extraction test
- Add JPEG malformed zero-length segment test

* feat: add multi-turn conversation history and tool execution
Major enhancement to the agent loop:
**Multi-turn conversation:**
- Add `ChatMessage` type with system/user/assistant constructors
- Add `chat_with_history` method to Provider trait (default impl
delegates to `chat_with_system` for backward compatibility)
- Implement native `chat_with_history` on OpenRouter, Compatible,
Reliable, and Router providers to send full message history
- Interactive mode now maintains persistent history across turns
**Tool execution:**
- Agent loop now parses `<tool_call>` XML tags from LLM responses
- Executes tools from the registry and feeds results back as
`<tool_result>` messages
- Agentic loop continues until LLM produces final text (no tool calls)
- MAX_TOOL_ITERATIONS (10) safety limit prevents runaway loops
- System prompt includes structured tool-use protocol with JSON schemas
**Types:**
- `ChatMessage`, `ChatResponse`, `ToolCall`, `ToolResultMessage`,
`ConversationMessage` — full conversation modeling types

* fix: address review comments on multi-turn + tool execution
- Add history sliding window (MAX_HISTORY_MESSAGES=50) to prevent
unbounded conversation history growth in interactive mode
- Add 404→Responses API fallback in compatible.rs chat_with_history,
matching chat_with_system behavior
- Use super::api_error() for error sanitization in compatible.rs
instead of raw error body (prevents secret leakage)
- Add missing operational logs in reliable.rs chat_with_history:
recovery, non-retryable, fallback switch warnings
- Add trim_history tests

* fix: address second round of review comments
- Sanitize raw error text in compatible.rs chat_with_system using
sanitize_api_error (prevents leaking secrets in error messages)
- Add chat_with_history to MockProvider in reliable.rs tests so
the retry/fallback path is exercised end-to-end
- Add chat_with_history_retries_then_recovers and
chat_with_history_falls_back tests
- Log warning on malformed <tool_call> JSON instead of silent drop
- Flush stdout after print! in agent_turn so output appears before
tool execution on line-buffered terminals
- Make interactive mode resilient to transient errors (continue
loop instead of terminating session)
