Motivation

• Prepare a new release by bumping the package version and updating packaging metadata for npm and PyPI.
• Standardize licensing to Apache-2.0 across JS and Python packaging metadata and classifiers.
• Improve wtcraft's --patch-agent-files behavior to reliably create and populate missing agent docs when scaffolding.

Description

• Bumped version to 0.3.4 in package.json, pyproject.toml, and src/wtcraft/__init__.py and added a CHANGELOG.md entry for 0.3.4.
• Switched license metadata from MIT to Apache-2.0 in package.json and pyproject.toml and updated the Python classifier to Apache Software License.
• Updated append_managed_block_if_missing in scripts/wtcraft and src/wtcraft/_shell.sh so missing files are created (with mkdir -p and the managed block written) and log Created and patched: <file> instead of skipping.
• Clarified README wording about required agent access and --patch-agent-files behavior to reflect the script changes.

Testing

• No automated tests were executed as part of this change.
