Add githubSkillTools to getAllToolDefinitions() so the searchable MCP
catalog matches TOTAL_MCP_TOOL_COUNT, which already counts them. The
GitHub skill tools were registered and counted but missing from the
catalog, so omniroute_tool_search could not surface them.
Adds regression tests at both layers: catalog aggregation and
client-visible discovery via the MCP client.

v3.8.40 cycle integration → main. All test gates green (Unit/Integration/Coverage/Node-compat/Quality-Ratchet). The only red check, 'PR Test Policy', is the test-masking heuristic firing on the cumulative ~57-commit release diff (legitimate assert consolidations already reviewed per-PR — Gemini CLI removal #5246, retired GPT models #5280, provider catalog refreshes); overridden with --admin per the documented release-PR convention. CodeQL/SonarQube advisory scans non-blocking; #5278's code already passed CodeQL on main. Homologated on VPS 192.168.0.15 (v3.8.40 healthy).
