MWPW-184913: Auto-link PRs to Jira tickets

[antonio-rmrz]

Resolves https://jira.corp.adobe.com/browse/MWPW-184913

• Automatically links GitHub PRs to Jira tickets when a PR is opened
• Extracts Jira ticket IDs (e.g., MWPW-12345) from PR title or branch name
• Verifies the ticket exists in Jira before creating the link
• Creates a remote link in Jira pointing back to the PR with format [repo] PR #Number: Title
• Skips gracefully if no ticket ID found or link already exists

Example:
