chore(ci): remove create-issue safe output from smoke tests

[Copilot]

Remove the create-issue safe output capability from smoke tests (smoke-copilot and smoke-claude) to prevent these workflows from creating GitHub issues.

Changes

Both smoke-copilot.lock.yml and smoke-claude.lock.yml:

• Removed create-issue: from safe-outputs frontmatter
• Deleted entire create_issue job (~590 lines each)
• Removed create_issue from needs arrays in add_comment and conclusion jobs
• Removed GH_AW_CREATED_ISSUE_* env vars from add_comment job
• Removed create_issue from config.json, tools.json, and validation schema
• Updated mermaid dependency diagrams

smoke-claude.lock.yml only:

• Removed mcp__safeoutputs__create_issue from allowed-tools list

Original prompt

remove safe output of github issues from all the smoke tests (smoke copilot, smoke claude etc.)
