Run ChunkHound QA script

Run structured QA tests on search tools

Verifying semantic and regex search implementations work correctly across all file types and languages without blocking or pagination bugs.

• · existing file paths for semantic/regex search
• · new test files to add
• · language/file type specifications

• · pass/fail status per test
• · indexing latency measurements
• · failure reproduction steps

• · semantic_search tool
• · regex_search tool
• · external MCP server

• · MCP server running
• · test files creatable in current directory
• · supported language parsers installed

• · embedding generation timeout (>3s wait)
• · language parser unsupported
• · pagination traversal incomplete
• · concurrent test blocking

• · explicit critical-stop-on-failure rule
• · latency measurement requirement
• · pagination validation against ripgrep
• · concurrent test coverage
