The so101 CLI runs under Node: `node bin/so101 --help` and `ports` no longer reach bun:sqlite #570

Piece 1 of 3 from #564, taken from closed pull #566. Start from its commits (git fetch origin refs/pull/566/head) rather than rewriting them.

Done:

• [ ] Software/so101/src/cli.ts imports server.ts only when serve runs, so no bun: import is reached from --help, ports, setup or teleop.
• [ ] src/cli-node.test.ts runs --help and ports under Node 22.6+ and passes in the forge check. It skips with its reason under older Node.
• [ ] A test walks the CLI's static imports and fails if any bun: module is reached.
• [ ] Files: src/cli.ts, src/cli-node.test.ts. No setup or teleop code in this pull.
