- New `get_schematic_component` MCP tool returns component position and
all field values with their label (at x/y/angle) positions
- Extends `edit_schematic_component` with optional `fieldPositions` dict
so callers can reposition Reference/Value/etc. labels in one call
- Adds 18 tests (6 unit, 12 integration) covering parsing, round-trips,
and edge cases
