Summary

Adds support for uv run command filtering to prevent incorrect routing through rtk run when users invoke uv run <tool>. This addresses issue #2841 where uv run (high-frequency Python command) was unhandled.

Changes

• New filter module: src/cmds/python/uv_cmd.rs - Handles uv sync, uv pip list/outdated, and uv run <tool> with routing to appropriate filters
• Discovery rule: Added pattern for ^uv\s+run\s+ in src/discover/rules.rs with 70% savings estimate
• CLI integration: Added Uv variant to Commands enum in src/main.rs with proper routing
• Meta-command registration: Added "uv" to RTK_META_COMMANDS to prevent fallback

Thanks for the patch, and apologies for the slow reply. The diff on this branch is the npm subcommand list and the ruff subcommand guard, and both have landed: PR #3087 (merged 2026-09-13) added the same fifteen npm subcommands so npm query and npm sbom no longer get run injected, and PR #3083 (merged 2026-09-08) added the ruff list with the check test moved into is_check_invocation. The uv work named in the title is not part of this diff, and uv is handled on develop already, where rtk rewrite "uv run pytest" returns uv run rtk pytest. Closing as already applied, but please comment or reopen if a part of this was missed.
