docs(reflow): rewrite getting-started as orientation; add WP tutorial
getting-started.md stays at the root as the 'welcome / who is this
for' orientation page, not classified as tutorial/how-to/reference/
explanation — it routes each audience to the right next doc. Three
paths (partners / WordPress users / developers) with working links
into the new Diátaxis structure.
Apply the source-availability factual fix from PR2 here too —
equalify-reflow is a public AGPL repo at EqualifyEverything/
equalify-reflow, not 'not yet publicly available'.
New: tutorials/process-your-first-pdf-with-wordpress.md — a guided
end-to-end walkthrough from plugin install through first converted
document, aimed at a WP admin. Uses the canonical 5 public phase
names (Extraction / Analysis / Headings / Translation / Assembly).
Based on the verified step sequence from the existing plugin how-to,
with reviewer next-step hooks into interpret-the-output and
provide-feedback.
