chore(release): refresh metadata for 2.1.1

[iziz]

Summary

• Refresh the bundled main, carrier, geocoding, and timezone metadata from Google libphonenumber v9.0.39 to v9.0.40 (upstream commit 9d77a67180fc7d342bf04da469968501317bbc91). Testing and short-number metadata are unchanged.
• Bump all Xcode projects and 13 podspecs to the metadata-only patch release 2.1.1.
• Record the upstream comparison and release validation in the changelog and metadata update log.

Source and validation

• Scheduled drift run: https://github.com/iziz/libPhoneNumber-iOS/actions/runs/36087389938
• Upstream source/resource comparison: 17 changed tracked files, all metadata or resources; no implementation or test source changes. Google master adds zero tracked changes beyond v9.0.40.
• Upstream test parity: 173 JS tests covered by 181 local Objective-C tests; API parity: 66 prototype methods covered by 93 selectors.
• All-in-one updater dry run and checked-in generation passed; v9.0.40 freshness and version consistency passed.
• SwiftPM default and Korean locale tests, release build, and three Xcode schemes passed locally. CocoaPods lint is running; CI status is required before merging.
