Regenerate the code wiki Output of `gitnexus wiki`, reshaped for wiki page addressing by tools/publish-wiki.sh.
Regenerate wiki from fresh index: covers guided mode; fix broken mermaid Re-synced all 19 pages from a GitNexus index that now includes src/guided/ and catalog.rs. The CLI Command Surface page documents the guided terminal wizard (Command::Guided, guided [DIR] [--edit FILE], --web/--guided resolution) and its entry-path mermaid diagram is corrected (a malformed node label rendered as a syntax error).
