feat: Domain 2 Phase 3-4 — wiki article tool, DCP compress toggle, Go sidecar deprecation

Phase 3: get_wiki_article tool wraps codesight_get_wiki_article MCP
(cached, persistent codebase wiki). DCP compress toggle on
get_codebase_overview (compress=true for large projects >50 files).

Phase 4: Deprecation markers on Go codecontext sidecar. Warning log
in callCodecontext(), deprecation comments in factory.ts and
docker-compose.yml. Sidecar remains functional — removal deferred.
