Rosetta Triage Review

Summary: This PR moves the existing "Supported IDEs and Agents" section from near the bottom of README.md to near the top (after the four-phases introduction), improving its discoverability for first-time visitors without changing any content.

Findings:

• The section content is identical to what was already in the README — this is a relocation, not an addition.
• The PR description says "Added a section" but the change is actually a move; the description is slightly inaccurate.
• No code, tests, or configuration files are affected.
• No breaking changes.

Suggestions:

• Consider updating the PR description to say "Moved the Supported IDEs and Agents section to the top of the README for better visibility" to accurately reflect the change.
