chore: release v1.6.3

[magyargergo]

Summary

Cuts the v1.6.3 release covering 78 commits since v1.6.2 (2026-04-18 → 2026-04-24).

Key themes:

• RFC Meta: Pure Scope-Based Resolution in the Semantic Model #909 Rings 1–3 landed — shared scope-resolution foundation (ScopeTree, DefIndex, ModuleScopeIndex, QualifiedNameIndex, MethodDispatchIndex, ClassRegistry/MethodRegistry/FieldRegistry, SCC-aware finalize, shadow-mode parity harness), ScopeExtractor driver wired through parse-worker + processor, per-language resolveImportTarget, REGISTRY_PRIMARY_<LANG> flag reader. Python + C# now run on the registry-primary call-resolution path.
• Cross-repo impact analysis — @repo MCP routing + group resources for multi-repo queries ([group] Cross-repo impact analysis, CLI and MCP tool (split 5/5 of #606) #794, feat: cross-repo impact analysis (#794) — @repo MCP routing + group resources #984).
• CLI repo-registry UX — analyze --name <alias> + duplicate-name guard, gitnexus remove, auto-infer name from git remote, sibling-clone drift detection by remote-URL fingerprint.
• Ingestion/embeddings — configurable large-file skip threshold (GITNEXUS_MAX_FILE_SIZE), GITNEXUS_INDEX_TEST_DIRS opt-in, analyze preserves existing embeddings by default + --drop-embeddings / --force, structural chunking, iterative AST DFS.
• Docker — signed UI + CLI/server images via docker-compose, RC build support, GHCR → Docker Hub mirroring, alpine → debian base.
• Fixes — Go receiver-method CALLS source IDs, FTS LOAD before INSTALL, groupImpact error bubbling, bm25 FTS-matched results, React component detection casing, detect-changes ENOBUFS + direct-CLI exposure, MCP disambiguation ranking.

See gitnexus/CHANGELOG.md for the full [1.6.3] entry.

Test plan

• CI green on release/v1.6.3
• Merge to main → auto-tag workflow / manual v1.6.3 tag push
• publish.yml publishes to npm with provenance and creates GitHub Release
• Attach hand-authored release notes to the GitHub Release
