Motivation

• Cut a 0.3.4 release for npm and PyPI with a coordinated version bump across packaging metadata.
• Make --patch-agent-files robust by creating CLAUDE.md/AGENTS.md when they don't exist instead of skipping.
• Align packaging metadata and classifiers with the new license choice for downstream repositories and indexes.

Description

• Bump package version to 0.3.4 in package.json, pyproject.toml, and src/wtcraft/__init__.py.
• Add a 0.3.4 entry to CHANGELOG.md describing the release tagging.
• Change project license from MIT to Apache-2.0 in package.json and pyproject.toml and update the PyPI classifier.
• Update the shell helper append_managed_block_if_missing in scripts/wtcraft and src/wtcraft/_shell.sh to create missing parent directories and write the managed block so CLAUDE.md/AGENTS.md are created and patched, and adjust log messages accordingly, and clarify this behavior in README.md.

Testing

• Built the Python package artifacts using python -m build to verify packaging metadata and the build backend, and the build completed successfully.
• Performed a basic import/version sanity check with python -c "import wtcraft; print(wtcraft.__version__)" which returned 0.3.4 as expected.
• No additional automated unit tests were added or changed in this PR.
