* feat(cli): add examples to ao preview --help (#387)
Update the preview command help to include a concise Examples section
covering the four common workflows:
ao preview
ao preview file:///home/aoagent/ReverbCode/index.html
ao preview http://localhost:5173
ao preview clear
Replace the workspace-relative path (./dist/index.html) in the Long
description with the absolute file:// URL pattern agents actually use.
Command syntax and behavior are unchanged.
Closes#387
* fix(cli): clarify no-arg preview fallback behavior in help text
Address review feedback on #388: the no-argument description now
reflects the daemon's actual behavior — autodetect the workspace
entry point, fall back to the session's existing preview target
when none exists.
