fix(cli): make 0pflow alias the root command and always update plugin

The shell alias now points to `npx -y --prefer-online 0pflow@dev` (without
`run`) so that `0pflow install`, `0pflow uninstall`, etc. all work.
`0pflow run` now always reinstalls the plugin to keep it in sync.

 Create a shell alias so users can just type `0pflow run`:
 ```bash
-alias 0pflow='npx -y --prefer-online 0pflow@dev run'
+alias 0pflow='npx -y --prefer-online 0pflow@dev'
 ```
 Use `--prefer-online` to ensure npx always re-resolves the `@dev` tag and pulls the latest build. For production, switch to `@latest` once we have a stable release channel.

 ### 13. ~~Consider global CLI install~~ — Decided against
 
-We want "always fresh" — every invocation should pull the latest dev build. The bash script sets up a shell alias (`alias 0pflow='npx -y --prefer-online 0pflow@dev run'`) which handles this. A global install would require explicit `npm update -g` to get new versions.
