Feature Request: Add support for `xcodebuild` and subcommands

[rursache]

iOS/macOS projects rely heavily on xcodebuild for compilation, testing, archiving, and code signing. These commands produce extremely verbose output that would benefit significantly from RTK's token-optimized filtering.

Suggested commands

• xcodebuild build — build a project/workspace
• xcodebuild test — run unit and UI tests
• xcodebuild archive — create an archive for distribution
• xcodebuild clean — clean build artifacts
• xcodebuild -showBuildSettings — display build settings
• xcodebuild -list — list schemes, targets, and configurations
• xcodebuild build-for-testing / xcodebuild test-without-building — split build and test phases
• xcodebuild -exportArchive — export an archive to IPA/PKG

xcodebuild is notoriously verbose — a typical build can produce thousands of lines of output, most of which is redundant for an LLM context window. Filtering down to warnings, errors, and build results would yield massive token savings.

I would be interested in this as well, there are a few projects out there doing something similar (making xcodebuild output better) so we don't have to reinvent the wheel:

• https://github.com/cpisciotta/xcbeautify
• https://github.com/xcpretty/xcpretty

There was even a PR on this repo that got closed:
