pikchr 1.1.0

New features

• Quarto and RMarkdown improvements: The knitr engine now supports fig.cap (figure captions with <figure>/<figcaption> in HTML), fig.alt (accessibility alt text via aria-label), and fig.align as standard knitr options.
• Non-HTML output support: Automatic PNG conversion for all non-HTML formats including DOCX, EPUB, and Typst (previously only LaTeX/PDF was supported).
• DPI-aware PNG conversion: The dpi chunk option (default 150) controls PNG resolution for non-HTML outputs.
• Error detection: Pikchr compilation errors now produce informative warnings with the error message, instead of silently embedding invalid markup.
• Quarto cross-referencing: Chunks with labels starting with fig- receive an HTML id attribute for Quarto cross-reference compatibility.

Improvements

• Replaced message(), warning(), and stop() with cli::cli_inform(), cli::cli_warn(), and cli::cli_abort() for consistent and user-friendly messaging.
• Removed dplyr, purrr, and rlang from Imports, replaced with base R operations for a lighter dependency footprint.
• Replaced tidyverse in Suggests with specific packages (rmarkdown).
• Updated authors list.
• Removed compiled objects (.o, .so) from src/.
• Cleaned up commented-out code and removed duplicate engine registration.
