feat: add the real-condition campaign runner

campaign.py takes buildbot nightlies (or a build of the pinned commit), the test content of tests/campaign/content.yml through romfetch, and runs core_probe for the files, boot, path, alias, variants and bench checks. A fixed rule table settles hle_fallback, required, path and aliases with the record ids as evidence, the rest goes to measurements/findings.jsonl. Resumable state, load, disk and budget guards, retries, content reference counting with an LRU cap, and an autorun job after the nightly.
