Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request integrates a new 'portless' entry into the registry, enhancing the system's ability to manage and verify this specific backend. The changes provide a clear definition of 'portless' functionality and establish a method for confirming its operational status within the system.

Highlights

• New Registry Entry: Added a new entry for 'portless' to the registry, specifying its backend as 'npm:portless'.
• Description and Test Command: Included a description for 'portless' and defined a test command to verify its installation and version.

Greptile Summary

This PR adds a new registry entry for portless, a tool that replaces port numbers with stable named .localhost URLs, backed by the npm backend. The single-file change follows the established pattern for npm-backed registry entries in this project.

• The file structure (backends, description, test) is consistent with other npm-backed entries such as registry/amp.toml and registry/bibtex-tidy.toml.
• The npm backend is appropriate here since portless is a Node.js CLI tool.
• The test assertion uses expected = "{{version}}" (bare version output), which is a common pattern. If portless --version actually emits a prefix such as portless/1.0.0 or v{{version}}, the smoke test will fail at CI time.

Confidence Score: 4/5

• This PR is safe to merge; it is a minimal, well-formatted registry addition with no logic changes.
• The change is a single new TOML file following established patterns. The only minor uncertainty is whether portless --version emits a bare version string (matching {{version}}) or includes a prefix — this would surface quickly in the existing registry CI tests.
• registry/portless.toml — verify the exact output of portless --version matches the expected pattern.
