v0.5.0

Highlights

• bggrep tool — search across background job logs (#4)
• bgtail delta tailing — tail only new output since the last read (#4)
• Project-local job logs — relative jobsDir keeps logs with the repo (auto git-excluded, migration-safe) (#1)

Also: CI now posts a sticky test-status report on every PR (updated in place, never stacking), and lint-test is a required merge check on main.
