🧪 Add tests for position_to_range in conversion module

[bashandbone]

🎯 What: The testing gap for the position_to_range function in crates/services/src/conversion.rs was addressed.
📊 Coverage: A unit test test_position_to_range was added to verify the happy path logic of converting start and end Position structs to a Range.
✨ Result: Test coverage for conversion.rs has been improved, and regressions on this straightforward conversion function can be caught.

Reviewer's Guide

Adds a focused unit test for the position_to_range helper to ensure it correctly constructs a Range from start and end Position values, improving coverage in the conversion module test suite.

File-Level Changes

Change	Details	Files
Add a unit test verifying that position_to_range correctly maps start and end positions into a Range struct.	Create test_position_to_range validating the happy-path behavior of converting two Position instances into a Range. Instantiate start and end Position values with distinct line, column, and offset fields to exercise typical input. Assert that the resulting Range preserves the original start and end positions via equality checks on the Range fields.	crates/services/src/conversion.rs

Position in the ast-engine is documented as using zero-based line/column values; using 1/2 here can be misleading for readers and future test extensions. Consider switching these to 0-based values (e.g., start at line 0) to match the documented semantics.
