devx: add a repo-managed pre-push CI gate

Add a versioned pre-push runner that mirrors the basic required CI suites we can execute locally, including version/changelog checks, Rust fmt/clippy/core checks, Python lint/typecheck/tests, docs, and the WASM gate.

Wire the runner into pre-commit at the pre-push stage, add make prepush and make hooks for manual use and hook installation, and document the workflow in the contribution guides.

Also add pre-commit to the development dependency set and refresh uv.lock so a synced dev environment can install and run the hook reproducibly.
