Reduces queryTimeoutDuration from 5s to 1s and limits root server fan-out to 3 randomly-selected servers per call.

Rationale for 1s timeout: max RTT to antipodes ~300ms, 3× that + 10ms processing ≈ 910ms, rounded to 1s.

Changes:

queryTimeoutDuration: 5s → 1s
rootServerList() now shuffles all 13 root servers and returns only 3
Removed redundant [:3] slices in resolveNSRecursive and resolveARecord

Resolver test suite: 9.7s (down from ~39s baseline)

closes #29

Reduces `queryTimeoutDuration` from 5s to 1s and limits root server fan-out to 3 randomly-selected servers per call. Rationale for 1s timeout: max RTT to antipodes ~300ms, 3× that + 10ms processing ≈ 910ms, rounded to 1s. Changes: - `queryTimeoutDuration`: 5s → 1s - `rootServerList()` now shuffles all 13 root servers and returns only 3 - Removed redundant `[:3]` slices in `resolveNSRecursive` and `resolveARecord` Resolver test suite: **9.7s** (down from ~39s baseline) closes #29

Updated timeout from 2s → 1s per feedback (3× max antipodal RTT ~300ms + 10ms processing = ~910ms, rounded to 1s).

Results (5 consecutive runs, resolver package only):

Before: ~39s
After: 9.5–10.7s (75% faster)

make check passes clean. Full suite ~15s total.
