fix: strip v prefix from version in Cargo.toml and package.json, fix bump script

Cargo requires plain semver (0.4.0), not v-prefixed (v0.4.0). The
bump-version script was passing the user's input directly without
stripping the leading 'v', breaking `cargo build` and `cargo publish`.

- Strip 'v' prefix in bump_version() using ${1#v}
- Fix version check to tolerate either form
- Correct all Cargo.toml and package.json files from v0.4.0 to 0.4.0
- Sync all Cargo.lock files

Note: Python pyproject.toml files remain at 0.3.4 — re-run the fixed
bump script to complete the version update.
