Subject: [PATCH] Optimize seed lookup from O(N) to O(1) in mock.js

Created a `SEED_MAP` to index the SEEDS array by device_id. This replaces
the linear `SEEDS.find(...)` lookup inside the `seed(id)` function with
a constant-time `SEED_MAP.get(id)`, significantly reducing lookup latency
for repeated calls.
