## Summary
Adds an internal React effects policy for `apps/fabro-web` so direct
component effects are exceptional and real external integrations move
behind purpose-named hooks.
The policy covers preferred alternatives such as render-time derivation,
SWR query hooks, mutation callbacks, URL/router primitives, keyed
resets, and `useSyncExternalStore`. It also documents guardrails for
`useMountEffect`, React 19 `useEffectEvent`, one-shot telemetry effects,
migration workflow, current hotspots, and review checklist.
## Verification
Not run; docs-only change.
