Stacked on #264.

Three small output tweaks from demoing grid setup:

• Yellow warning: prefix. New ctx.Warn / ctx.Warnf helpers write warning: in the terminal's own yellow (ANSI 3, bold) followed by the message in the normal colour, the same as cargo and Homebrew. Colour is dropped when stderr isn't a terminal, so piped output and tests see plain warning: … text.
  • Every existing warning: line goes through them: grid, model, model environment, predict, ssh, auth and volume transfer. Volume transfer used to print Warning: with a capital W; it now matches the rest.
  • The auth store's warnWriter callbacks receive the bare message and the CLI adds the prefix.
  • Harness plans carry warnings in a new Plan.Warnings field instead of Notes strings with a warning: prefix baked in. Setup prints warnings before notes.
  • LogLine / Logf are unchanged plain writers; nothing is coloured implicitly.
• No statusLine note. Claude Code setup no longer prints "Existing statusLine in … left unchanged; for auto routes, the serving model will be shown after each response through a Stop hook instead." The behaviour is unchanged (a user's statusLine is kept and the served model comes from a Stop hook). It was the last plan note, so Plan.Notes and its print loop are removed.
• Spacing around the setup notice. A blank line before and after "Modifies harness settings…" separates it from the notes above and the prompt below.

Before:

warning: you are running /tmp/…/baseten, but baseten on your PATH is /opt/homebrew/bin/baseten; harnesses will run the former
Existing statusLine in ~/.claude/settings.json left unchanged; …
Modifies harness settings to set Grid as the gateway with your configured models.
To remove Grid, run baseten grid teardown.
┃ Set up Grid?

After (warning: in bold yellow, the rest unchanged):

warning: you are running /tmp/…/baseten, but baseten on your PATH is /opt/homebrew/bin/baseten; harnesses will run the former

Modifies harness settings to set Grid as the gateway with your configured models.
To remove Grid, run baseten grid teardown.

┃ Set up Grid?

Existing tests still match the plain warning: text. Two harness tests now read Plan.Warnings, and the statusLine tests assert the note is gone while still checking the user's statusLine is kept. Test_Grid_Setup_RealHarness and Test_Grid_ClaudeServedModel_RealClaudeCode fail locally the same way they do on main.
