[gobby-cli-#725] chore: regenerate codewiki + general wiki, capture parity+ evidence

Clean end-to-end regen on a wiped, freshly-init'd vault with v-next binaries
(gcode 1.1.0 / gwiki 0.4.0, HEAD 15972ef) and the restored daemon vision path.

Codewiki: 372 file + 67 module + repo docs; all 134 broken-AI-lane stubs healed
(exposes-N-symbols and has-no-indexed-API both 0); #727 content-only markdown
pages pruned; 55 module-level mermaid diagrams; bounded frontmatter; 0 real
broken links after a scoped re-run stripped reused pre-#726 absolute-path links.
One honest-degraded page remains (_ownership.md: no CODEOWNERS + bounded blame).

General wiki by the book: ingest url/file/inbox + multimodal logo (vision
extracted), index with zero degradations, hybrid RRF search (bm25+semantic),
WP2b compile explainer via daemon synthesis. Retrieval Q&A answered via
search+read and thin ask on both daemon and direct (LM Studio) routes, incl.
an honest no-hallucination refusal. Agent research-deposit loop verified.

Evidence under docs/evidence/wiki-parity-2026-06/. Follow-ups: #732 (wikilink
syntax in symbol summaries), #733 (compile checkpoint unreachable on fresh vault).

+  - The gcode and gwiki search stacks both combine three independent retrieval
+  - signals — pg_search BM25, Qdrant semantic vectors, and a FalkorDB graph
+  - relevance boost — and merge their ranked lists with Reciprocal Rank Fusion
+  - (RRF). RRF is rank-based, so it is robust to incomparable per-engine scores:
+  - each engine contributes 1/(k + rank) per document, and the sums determine the
+  - final order. Any engine can be absent (graph down, embeddings off) and the
+  - fusion still returns a sensible ranking from the remaining signals.
