A test pins what the forge CLI prints: columns line up with wide characters, and piped output carries no colour #6875

src/cli/out.ts formats every forge CLI table and line with the TUI's displayWidth and theme, and promises that every line survives grep. No test imports it.

Done:

• [ ] test/cli-out.test.ts: createOut with a fake stdout that is not a terminal prints no ANSI escape. With NO_COLOR set it prints none even on a terminal. A terminal without NO_COLOR paints.
• [ ] table lines up a column holding a CJK name and an emoji with one holding ASCII, measured with displayWidth. A column's hard cap cuts a cell, and right-aligned numbers end at the same column.
• [ ] Width is 80 when there is no terminal. err goes to stderr, not stdout.
• [ ] A cell holding an escape sequence is printed inert, so a repository name cannot repaint the terminal. If it isn't, fix it in out.ts.

This adds a test file only; change the code only where the test finds a hole, and say so in the pull. It touches no api.ts, MCP tool or docs/MCP.md, so it waits on none of the pulls there.

Before pushing: bun x tsc --noEmit and the test you add. Tests pass now in and never read the wall clock.
