Add a one-shot 'VSCode - Compile' task and wire it as preLaunchTask
so pressing F5 always compiles kilo-vscode before launching, regardless
of whether the background watch tasks started on folder open.
- Add watch-cli.ts script that watches packages/opencode/src/ for changes,
triggers a rebuild (bun run build --single --skip-install), and copies
the new binary to packages/kilo-vscode/bin/kilo
- Add watch:cli npm script in kilo-vscode package.json
- Add 'VSCode - CLI Watch' task in .vscode/tasks.json
- Include CLI watch in the composite 'VSCode - Watch' task so it runs
automatically when launching the extension via F5
