Subject: [PATCH] fix: raise default ttl to 5m, add 1h preset

A 60-second default TTL forces resolvers to re-walk the DHT (16/20
quorum) on every cache window expiry, producing the ~30s tail latency
debugged in ipfs/kubo#11301. Align the create-form default with Kubo's
own `ipfs name publish --ttl` default and add a 1h preset for users who
publish infrequently.

Closes #48
