Release v0.3.0

What's Changed

Bug Fixes

• Require Python 3.13+ across all pyproject.toml manifests to resolve a SIGKILL crash caused by wasmtime>=43 being incompatible with Python 3.9
• Fix MQTT topic patterns in Python and Node loopback, speed monitor, and vehicle examples to match the correct broker topic structure for private/public messages
• Fix identity artifact field names in Node examples (device_id → deviceId, expiration_time → expirationTime) for consistency with the API
• Add type=float to --lat/--lon CLI arguments in Python examples to prevent string comparison errors at runtime

Project / Build

• Bump version to 0.3.0 across all manifests (VERSION, CMakeLists.txt, pyproject.toml, package.json files)
• Rename npm and Python workspace packages from etx-starter-kit to etx-sample-client
• Add uninstall-js Makefile target hooked into install-js and purge
• Add j2735codec/package.json and package-lock.json; update root lock files
• Remove stale .python-version pin (3.9); update uv.lock to reflect Python 3.13 constraint and wasmtime 43.0.0
• Update .gitignore: replace certs/ with registrations/, add .claude/

Documentation

• Fix all GitHub URLs from 5GRealityLab/etx-starter-kit to Verizon/EdgeTransportationExchange_SampleClient
• Update cert output path references from certs/ to registrations/ across all READMEs and example run commands
• Fix typos, remove emoji from headings, and improve markdown formatting consistency across root, etx/, and example READMEs
• Add usage hints clarifying that speed monitor and vehicle examples each require a separate registration profile
