VS-13 Release Readiness (E2E Critical Flows + Docs + Bug Bash) #48

What to build

Validate the core geo product flows end-to-end, resolve the top bugs surfaced in a focused bug bash, and leave the codebase in a state where a new contributor can onboard and run quality checks without manual intervention. Auth and premium E2E flows removed from scope.

Acceptance criteria

• E2E tests cover: map loads and renders H3 zones, zone selection opens detail panel, period selector updates the map, dashboard KPIs render and link to map
• A bug bash is run against the full geo flow; all P1 bugs are resolved before sign-off
• Contributor guide documents: one-command local setup, env var requirements, test commands, and how to add a new map layer
• vite build --report shows no unexpected large chunks; lazy loading is confirmed for heavy map and visualisation modules
• Release checklist is signed off by at least one other team member
