Separate omnibus and post-hoc differential regulation results

[Copilot]

Multi-group differential regulation needs to distinguish the overall omnibus test from pairwise post-hoc comparisons. The output now exposes each test’s adjusted significance separately for plotting and downstream analysis.

• Result fields: rejected remains the omnibus decision; posthoc rejected records the pairwise decision.
• Correction and schemas: Accumulate corrected pairwise results and validate the post-hoc decision in ANOVA and ANCOVA outputs. Method identifies the selected omnibus test.
• Example: Update the multi-group example to plot pairwise fold changes against pairwise p-values.

omnibus = results[["identifier", "F-statistics", "padj", "rejected"]].drop_duplicates()
pairwise = results[
    ["identifier", "group1", "group2", "posthoc pvalue adj", "posthoc rejected"]
]

• Fixes Check differential regulation results table for more than two groups #91
