Add Kiro as a URI-based file opener option

Feature Request

Add Kiro as a supported file_opener option in the UriBasedFileOpener enum, alongside VS Code, VS Code Insiders, Windsurf, and Cursor.

Motivation

Kiro is an IDE that supports the kiro:// URI scheme for opening files. Users who use Kiro as their primary editor should be able to set file_opener = "kiro" in their config.toml so that file citations in the TUI link directly into Kiro.

Proposed Implementation

I have a working implementation on my fork: alohaninja/codex@add-kiro-file-opener

The change is minimal (2 files, 6 lines added):

• codex-rs/config/src/types.rs — Add Kiro variant to UriBasedFileOpener enum with kiro:// URI scheme
• codex-rs/core/config.schema.json — Add "kiro" to the allowed enum values

Both cargo check -p codex-config and cargo check -p codex-core pass with these changes.
