Releasing new version 14.11.0.

What's Next

PR Author: Be sure to create and publish a GitHub Release pointing to trunk once this PR gets merged,
copy/pasting the following text as the GitHub Release's description:

### New Features

- New `macos_verify_code_signing` action, asserting that macOS artifacts are signed, signed by the expected authority, accepted by Gatekeeper, and have a notarization ticket stapled to them. Handles `.app` bundles and `.dmg` disk images, picking the checks that apply to each. [#757]

### Bug Fixes

- `StringsFileValidationHelper.find_duplicated_keys` now parses unquoted keys/values and inter-token comments, matching the grammar `plutil` accepts, instead of raising `Invalid character`. This lets `ios_lint_localizations`' `check_duplicate_keys` work on `InfoPlist.strings`-style files. [#741]
- `ios_lint_localizations`' `check_duplicate_keys` now warns and skips, rather than crashing, on a file that parses as a property list but isn't a tokenizable flat `.strings`. [#741]
- `L10nHelper.merge_strings` now prefixes keys via a comment-aware tokenizer, so unquoted keys, unquoted values, and keys behind an inter-token comment are prefixed in the output consistently with the reported keys. [#741]
- Bump `fastlane` to `~> 2.237` to pull in `excon >= 1.5.0`, fixing CVE-2026-54171 / GHSA-48rx-c7pg-q66r. [#754]
- `upload_github_release_assets`: make release lookup more resilient by falling back to GitHub's direct release-by-tag lookup when the releases list does not include the requested release. [#753]

### Internal Changes

- Added regression coverage for `upload_github_release_assets` direct release lookup errors. [#755]
- Centralized `.strings` duplicate-key detection behind `StringsFileValidationHelper.scan_for_duplicate_keys`, returning a `[:scanned | :unsupported_format | :unscannable, payload]` tri-state that callers can map to their own warn-and-skip vs fail-closed policy. [#741]
- `L10nHelper.strings_file_type` and `StringsFileValidationHelper.scan_for_duplicate_keys` accept `assume_valid:` to skip a redundant `plutil -lint` when the caller has already parsed the file. [#741]
- Bumped development Ruby version to 3.4.9 [#729]
