fix(github/deployment): Support validated hotfix deployments

[herokwon]

🔍 Description

Allow failed Production deployments to be recovered through a validated hotfix deployment strategy.

🗝️ Key Changes

Validate Hotfix Deployments

• Recognize scoped fix PR titles targeting main as Production hotfixes.
• Require the latest Production Deployment to have a failure or error status before proceeding.
• Upload and deploy a Worker Version for validated hotfix deployments.

Separate Deployment Strategies

• Separate Worker Version upload and deployment operations based on the resolved deployment strategy.
• Preserve the existing Release-based Production and Preview deployment flows.

• Versions & deployments · Cloudflare Workers docs

➕ Additional Information

• Scoped fix titles such as fix(github/deployment): are supported.
• Hotfix deployment is rejected when no Production Deployment exists or the latest Production Deployment did not fail.
