Implemented, reviewed, merged, and validated.

Summary:

• Added ToolExecutionContext with call_id, batch_id, and call_index.
• Changed Tool execution APIs so Tool::execute / ToolServer::call_tool receive execution context.
• Worker assigns one response-local batch id per approved tool-call batch and preserves LLM-returned call order with call_index.
• Approved tool calls still execute in parallel; no scheduler, same-file mutex, mutation queue, conflict solver, or parallel_tool_calls=false behavior was added.
• ToolCallInfo / ToolResultInfo expose context metadata.
• Macro-generated tools can receive ToolExecutionContext as a non-schema parameter; context is not exposed as an LLM JSON argument.
• Built-in tools and tests were migrated to the new API.

Implementation:

• Coder commit: d8aed7b tool: add execution context
• Reviewer approved with no blocking findings.
• Merge commit: 4744548 merge: add tool execution context

Validation after merge:

• cargo test -p llm-worker --test parallel_execution_test test_tool_execution_context -- --nocapture
• cargo test -p llm-worker --test parallel_execution_test test_parallel_tool_execution -- --nocapture
• cargo test -p llm-worker --test tool_macro_test -- --nocapture
• cargo check -p llm-worker -p tools -p ticket
• cargo fmt --check
• git diff --check
• cargo run -q -p yoi -- ticket doctor
• cargo check --workspace
• nix build .#yoi

Residual note:

• batch_id is Worker-local and not a durable/global external artifact key.
