test(hook): cover option-bearing uv runs in Claude chains

[GratefulDave]

Summary

• add registry coverage for uv run --extra dev pytest, the option-bearing form skipped by RTK 0.43.0
• add an end-to-end Claude PreToolUse regression for the frequent compound shape cd ... && uv run --extra dev pytest ... 2>&1 | tail ...
• lock in develop's dedicated rtk uv routing so this high-frequency Claude Code command keeps receiving an updatedInput rewrite

Related to #294. The production routing landed in #1405; this PR covers the stable-version regression at the Claude hook boundary.

Test plan

• cargo fmt --all --check && cargo clippy --all-targets && cargo test
• cargo test uv_run
• Manual testing: exact Claude Bash payload rewrites uv run --extra dev pytest ... to rtk uv run --extra dev pytest ... inside the compound chain

Important: Targets develop as required by the contribution guide.
