fix(hook): propagate global flags through Claude rewrites

[coyaSONG]

Summary

• propagate --ultra-compact and --skip-env from rtk hook claude into each rewritten RTK command
• preserve environment-prefixed and compound rewrites without modifying raw pipe consumers or rtk arguments
• add CLI parsing and hook regression coverage

Fixes #2984.

Test plan

• cargo fmt --all --check
• cargo clippy --all-targets
• cargo test --all
• Manual testing: Claude PreToolUse payload returns rtk --ultra-compact --skip-env next
