LLM Contributions: Implementation and description were produced with an LLM tool, directed and reviewed by the requester.

Layout::height() was the sum of each line's line_height, so a gap from moving a line down with BreakerState::set_line_y (e.g. below a float) was not counted. The height is now the bottom of the bottom-most non-empty line (line_y after the line, tracked as a max in BreakerState), so it's unchanged when lines aren't moved. Using block_max_coord instead was tried but changes heights under quantization (it's rounded), failing the line-height tests.

Adds a test that fails without the fix.

Changelog

Fixed

• Layout::height() now includes gaps from lines moved down with BreakerState::set_line_y.
