release: cut v1.0.0 — first public release

Version bumped to 1.0.0 / 7. No code changes beyond the version — 1.0.0 is the
accumulated v0.1 → v0.6 work (all V1 screens, full event read, filter, settings,
onboarding polish) declared release-ready. CHANGELOG [1.0.0] summarises the
shipped feature set; ROADMAP/STATE mark V1 complete.
