Learnings

Clarification: Use `./bin/dev` not `rbenv exec bin/dev`

Context: I clarified in README.md that ./bin/dev is the preferred command to start the development server, after confirming rbenv exec bin/dev causes issues (previously logged Apr 8 & Apr 13).
Resolution: I updated README.md to reflect ./bin/dev as the primary command and added a note about specifying the PORT environment variable if needed (e.g., PORT=8000 ./bin/dev).
Learning: I learned to ensure documentation (README.md, PLANNING.md) accurately reflects the working commands discovered during troubleshooting and development, including common variations like specifying a port or necessary environment variables. Keeping documentation consistent with learned best practices for my specific project environment is important.
