Fixed
- Resolve path-qualified wikilinks such as [[entities/kalman-filter]] across lint, graph extraction, backlinks, hub ranking, and wiki statistics.
- Keep qualified paths strict so an invalid path cannot silently bind to a same-stem page elsewhere.
- Preserve unresolved targets in backlinks and top-linked reports so broken-link diagnostics remain visible.
- Add 48 focused resolver and reporting checks.
No wiki schema migration is required.
