How AI was used in this PR

I used Opus 5 for implementation and tests.

Proposed Changes

#4702 renames the "latest" WordPress version option to "Auto-update" in both UIs. This PR updates the naming in the CLI to keep it consistent.

--wp auto-update now selects that mode, matching what the apps show. --wp latest keeps working as an alias too, so existing scripts and blueprints are unaffected.

latest is still the internal value, and it still names a cache directory, a segment of the wordpress.org download URL, and the persisted site setting. The alias is resolved where the CLI parses input and never reaches storage.

Two side effects:

• blueprint use --wp was not validated at all. It needed the alias mapping anyway, and the shared coercion brings validation with it, so a bad value now fails at parse time instead of throwing from inside the download helper.
• The interactive version picker in site create said latest (7.1); it now says Auto-update (7.1), matching the apps.

Testing Instructions

• Build the CLI with npm run cli:build

The new value works

node apps/cli/dist/cli/main.mjs site create --path ~/Studio/wp-alias --name wp-alias --wp auto-update --no-start

• check ~/.studio/cli.json: the site should have "isWpAutoUpdating": true.

latest still works

node apps/cli/dist/cli/main.mjs site start --path ~/Studio/wp-alias
node apps/cli/dist/cli/main.mjs config set --path ~/Studio/wp-alias --wp 6.9
node apps/cli/dist/cli/main.mjs config set --path ~/Studio/wp-alias --wp latest

--wp 6.9	--wp latest

isWpAutoUpdating should go false, then back to true. The site has to be running
for config set --wp to apply, so studio start it first.

Help text

site create --help, config set --help and blueprint use --help should all
describe auto-update and mention that latest is accepted.
