Adds a zero-dependency `frontend-contract` bin that serializes the real
NoticeStatus variants and FrontendEvent payloads, scripts/gen-contract.mjs
which emits the committed src/services/contract.ts, and a CI job that
regenerates it and fails on a non-empty diff. events.ts now derives its
event map from the generated contract instead of hand-typed shapes.
Drive the production home traffic graph through embedded WebDriver in an
isolated optimized measurement build. Record attributed WebContent and main
process CPU/RSS distributions across foreground, hidden and restored phases.
Keep replay, raw reports, independent-run comparison, cleanup checks and
focused validation available through project commands. Normal release builds
exclude the automation service and measurement entry points.
