Problem

pdflatex can wrap long error lines at 79 columns and often ends failed runs with Emergency stop. noise, so preview.nvim's built-in preset can surface truncated or misleading failure notifications. The preset also lacked fixture-backed coverage for the audited failure shapes in #89.

Solution

Set max_print_line=10000 on the preset, add a pdflatex-specific failure summary that prefers ! LaTeX Error, then non-noise file:line, then non-noise ! lines, and fall back to the compiler's generic message when nothing trustworthy is present. Add fixture-backed preset tests covering the audited success, fallback, noisy, wrapped, and canonical failure cases.
