Emitter Prep for PR

Prepares language emitter changes for pull request by running build/format/lint, checking for a changeset, and pushing to the remote branch.

This skill is for language emitter packages only:

• http-client-python
• http-client-csharp
• http-client-java

Do NOT use this skill for core TypeSpec packages (compiler, http, openapi3, etc.).

Workflow

Step 1: Determine the emitter package

Figure out which emitter package the user is working on from context (cwd, recent changes, or ask). The package will be under packages/<package-name>/.
