feat(cli): default-aggregation for topic list + notification list

ships v0.5.0 phase 1.

omitting --mesh on these read verbs now routes through
/v1/me/topics and /v1/me/notifications instead of prompting
the user to pick a mesh. behavior preserved for explicit
--mesh foo.

implementation: resolveMeshForMint helper in commands/me.ts
silently picks the first joined mesh for apikey-mint when
flags.mesh is null. /v1/me/* endpoints resolve the user from
the apikey issuer regardless of which mesh issued the key, so
mint location is irrelevant — only the user identity matters.

help text updated to reflect the new default.

phase 2 (task list, state list, memory recall) needs /v1/me/*
aggregator endpoints first; deferred.
