docs: update AGENTS local testing workflows

[shaypal5]

Summary

• document additional local-testing make targets already present in Makefile
• document parallel test options supported by scripts/test-local.sh
• add CACHIER_TEST_CORES environment-variable workflow example

Why

Keep AGENTS.md aligned with actual repo workflows/commands so automation and contributors use the same entry points.

Changes

• add make test-mongo-inmemory
• add make test-mongo-also-local
• add make services-logs
• add -p/--parallel and -w/--workers options
• add CACHIER_TEST_CORES="mongo redis" ./scripts/test-local.sh example

Pull request overview

Updates contributor/agent documentation in AGENTS.md to better reflect existing local-testing workflows (Make targets and scripts/test-local.sh options) used across Cachier’s multi-backend test matrix.

Changes:

• Document scripts/test-local.sh parallel options (-p/--parallel, -w/--workers) and CACHIER_TEST_CORES env var usage.
