SHARD-WP-0003 T4. Wiki compiler: git-canonical Markdown source -> static HTML
(derived publish/projection, not the canonical store). Two new insights atop
the git-IS-store home case: compile-to-static = clean canonical-source vs
derived-output separation (attach source repo, UC-37/UC-56), and a third
federation flavor -- git replication + XML-RPC change-ping (pinger), beside
fedwiki fork/journal (UC-72) and Wikibase SERVICE (UC-74). UC-79. Enriched
UC-31/56/37/33. Marks T4 done. Feeds SHARD-WP-0002 T4/T6/T14.
