v0.1.2

• Skip station-corrections kind: tide reference ports in the registry overlay (they have no current series; they read as false name-drift warnings)
• Record dropped stations in a skipped[] array in the bundle (label, key, reason) so coverage is auditable from the output alone
• New --user-agent CLI flag; the default UA stays an honest chs-constituents/1.0 (see README)
• station-corrections dependency raised to ^2.2.0
