[STORY] v4-S27: Regression test suite for v3 projects

[raifdmueller]

User Story

As a project maintainer, I want automated tests that verify v3 projects produce the same output on v4.

Acceptance Criteria

Given a set of v3 sample projects with known output
When each project is built with v4
Then generateHTML output matches v3 output (excluding timestamps)
And generatePDF output is generated without errors
And no unexpected warnings or errors appear

Priority: Must

Epic: v4-E5 (#7)

Blocked by: v4-E1, v4-E2

Analysis

Test Projects Needed

1. docToolchain's own documentation (src/docs/) — generateHTML, generateSite
2. A minimal project with just one .adoc file — smoke test
3. A project using Confluence publishing config — config parsing test
4. A project with jBake metadata headers — site generation test

Comparison Strategy

• HTML structure comparison (headings, sections, links) — not pixel-perfect
• PDF generation succeeds without errors
• Site menu structure matches
• No warnings/errors that didn't exist in v3
