TRAC-614: Add project delete command to catalyst CLI

[jordanarldt]

What/Why?

Adds catalyst project delete for permanently removing a BigCommerce infrastructure project.

• --project-uuid <uuid> deletes a specific project; without it, the user picks from a list (with [linked] marker and a Cancel option).
• --force skips the destructive-action confirmation prompt.
• If the deleted project matches the linked one in .bigcommerce/project.json, projectUuid is cleared from config.

Targets feat/trac-137-catalyst-cli so it lands as a follow-up to the larger CLI migration PR.

Testing

• 12 new unit tests covering: --force, confirmation accept/decline, interactive selection with [linked] marker, Cancel selection, empty list, linked-vs-other config behavior, missing credentials, 403, 404.
• pnpm test, pnpm lint, pnpm typecheck all clean (240/240).

Migration

None.
