Add detailed plan for migrating to moduleResolution node16/nodenext with
file extensions in imports.
This plan addresses:
- #154 - Upgrade moduleResolution from node to node16/nodenext
- #110 - Published ESM code has imports without file extensions
- #64 - expressions: ERR_MODULE_NOT_FOUND attempting to run example demo script
- #146 - Can not import @actions/workflow-parser
The migration will:
1. Upgrade TypeScript to 5.7+
2. Enable rewriteRelativeImportExtensions
3. Add .ts extensions to all relative imports
4. Update JSON imports to use import attributes
Implementation will begin after pending PRs are merged to avoid conflicts.
