fix(mcp): remove top-level anyOf from tool schemas for Claude API compatibility

sdsrss · claude · sdsrss · commit c08d6f33e6f8 · 2026-03-22T20:12:18.000+08:00
find_similar_code and ast_search used top-level anyOf in inputSchema which
is unsupported by Claude API, causing subagent 400 errors. Changed to
required:[] with existing runtime validation. Bump to v0.7.7.
