Generate PNG plots for temporal analysis results — generate_temporal

Creates two publication-quality plots:

temporal_prevalence.png – line chart showing theme prevalence (\
temporal_emergence.png – lollipop/timeline chart showing when each theme first appeared in the data.

Usage

generate_temporal_plots(
  temporal_results,
  output_dir,
  methodology_mode = NULL,
  run_id = NULL,
  max_inline_themes = 30L
)

temporal_results: List returned by analyze_temporal_patterns
output_dir: Directory where PNGs will be saved (created if needed)
methodology_mode: Optional character. When supplied, adds a caption to each plot identifying the mode + run id.
run_id: Optional character: run identifier.
max_inline_themes: Integer; the temporal emergence chart filters to the top-N themes by entry count when more themes than this exist. an earlier version of the chart rendered every theme (4,059 codes on a large run -> 2.8 MB vertical wall of text). Default 30L. Set very high (e.g. 10000L) to disable filtering.
