Add pact replay mismatch summary output

[h1065153539-create]

Summary

• adds --replay-summary for human-readable OpenAPI pact replay mismatch triage
• adds --replay-summary-json for CI/chat-ops artifacts
• summarizes failed interactions by method, path, expected/actual status, and response body shape differences
• includes passing and failing replay fixtures under tools/fixtures/
• documents pact replay triage usage in docs/OPERATIONS.md

Validation

• Lupa-backed Lua execution validated tools/openapi_pact.lua --replay-summary tools/fixtures/pact_replay_fail.json and confirmed the output includes POST /auth/login, status mismatch, and response body shape differences.
• Lupa-backed Lua execution validated tools/openapi_pact.lua --replay-summary-json tools/fixtures/pact_replay_fail.json; the output parsed as JSON with 2 failed interactions.
• Lupa-backed Lua execution validated tools/openapi_pact.lua --replay-summary tools/fixtures/pact_replay_pass.json; the output reports 0 failing interactions.
• git diff --check passed.
• python3 build.py was run in WSL and produced diagnostic/build-31d4d08b.logd plus diagnostic/build-31d4d08b.json for change commit 31d4d08b.

Build note

The repository-wide WSL diagnostic build recorded failures for unavailable/shimmed multi-language tools in this validation environment (cargo, npm, go, make, cmake, javac, ruby, luac, ghc). The required encrypted diagnostic artifact was still generated and included.
