ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This adds a new px0 integration that is automatically offered when its CLI is installed and launches a detached local server/browser workflow with persistent server-side effects. It also changes fallback preferred-editor selection for some installations, so the behavior and lifecycle warrant human review. You can add or adjust custom eligibility rules. Learn more. |

<Document px0's persistent process lifecycle.
The picker routes px0 through the shared detached launcher. Each selection can leave a px0 server running after its tab closes. The PR description discloses this behavior, but no user-facing README or documentation entry describes it. Add a short note that each launch creates a persistent local server and that users must terminate it explicitly when finished. Process reuse or termination is not required by the current editor contract.

The Open picker has no way to open a project or file in px0, an open-source, browser-based IDE focused on code review, with Git and GitHub integration. This lets people inspect agent changes in px0 directly from T3 Code.
Registers px0 in the shared editor definitions and adds its
[0]icon to the picker. It appears when the server discovers the installedpx0CLI and launches aspx0 <path>, using the existing direct-path launcher. File targets, includingpath:line:col, are passed unchanged. No new dependency or launcher machinery is needed.Notes:
