Anchor the ignore rule to the repository root.

plan/ matches directories named plan at any depth below this .gitignore. This is broader than the stated top-level scope and can hide unrelated nested files from version control. Change it to /plan/.

In @.gitignore at line 15, Update the plan ignore rule from an unanchored
directory pattern to a repository-root-anchored pattern, so only the top-level
plan directory is ignored and nested directories with the same name remain
trackable.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Forward caller geometry to ggplotly().

Line 668 always creates an 800×600 Plotly figure. A caller that sets another width or height gets the wrong HTML geometry. The condition-label calculation can also select a layout for a width that the Plotly figure does not use.

Add width and height parameters to .convertGgplot2Plotly(). Pass them from every dataProcessPlots() conversion call.

Proposed fix

In `@R/dataProcessPlots.R` at line 668, Update .convertGgplot2Plotly() to accept
width and height parameters and pass them to ggplotly() instead of hard-coding
800×600. Update every dataProcessPlots() call to this conversion helper to
forward its caller-provided width and height, keeping condition-label layout
calculations aligned with the resulting Plotly dimensions.
