engine/ package: EngineKernel (in-process page store with per-page version history; create/edit-as-version, recoverable delete-tombstone, keys, current_rev) + wikilink extraction + in-shard link resolution / red-link detection (EC-1..EC-4). Reuses model/provenance; git-IS-store backing slots in later. 6 tests green, pyflakes clean, full suite green. Marks T1 done. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
